When you are accelerating at a constant torque you will see linear increase in power and therefore in battery current. What are phase amps exactly? They''re talking about a motor that
Line Voltages and Phase Voltages in Star Connection. We know that the Line Voltage between Line 1 and Line 2 (from fig 3a) is. V RY = V R – V Y . (Vector Difference) Thus, to find vector of V RY, increase the Vector of V Y in reverse direction as shown in the dotted form in the below fig 2. Similarly, on the both ends of vector V R and Vector V Y, make perpendicular dotted lines
Line & Phase Current and Line & Phase Voltage in Delta (Δ) Connection. The current of Line 1 can be found by determining the vector difference between IR and IB and we can do that by increasing the IB Vector in reverse, so that, IR and IB makes a parallelogram.
The relationship between line and phase currents refers to how the current flowing in the lines connecting power sources to loads differs from the current flowing through individual
Battery current is the current getting drawn from the battery by the controller. Phase current is the current sent to the motor by the controller. I know controlling phase current can provide the smoothest throttle response (vs speed throttle which is the worst or torque which is better than speed) but I''m not certain why exactly. I
Relation between line current and phase current. In Y-connected supply system, each line conductor is connected in series to a separate phase as shown in Fig. (a). Therefore, current
Battery current is the current getting drawn from the battery by the controller. Phase current is the current sent to the motor by the controller. I know controlling phase current can provide the
Unlike single-phase systems, which use a single alternating voltage, three-phase systems use three voltages or currents that are phase-shifted 120 degrees relative to one another. This
Unlike single-phase systems, which use a single alternating voltage, three-phase systems use three voltages or currents that are phase-shifted 120 degrees relative to one another. This section discusses the fundamental arrangement of three-phase systems, their representation using phasor diagrams, and the distinction between line and phase values.
I have seen so many forum discussions talking about battery current to phase current ratio and I still cannot see how the phase currents added together does not equal the battery current. The dc batttery current ultimately gets split three ways via the mosfets to the phases. The current through the battery has to equal the currents in the three
Line voltage = Phase voltage. What is line current: The measure of current in one phase before the star or delta arrangement of the component is called line current (typically input current in motor or output current in the alternator). In three phase balanced system, it may be R phase current or Y phase current or B phase current.
Relation between line current and phase current. In Y-connected supply system, each line conductor is connected in series to a separate phase as shown in Fig. (a). Therefore, current in a line conductor is the same as that in the phase to which the line conductor is connected.
The current leaves the battery and goes through one of the mosfets through one one phases and then through the other phase and back to the negative terminal of the battery.
When measuring the current, the measured value will be the average value of this current ripple. Now, let''s see why the input current (DC bus) can be different from the output current (motor phases). As mentioned, the current always flows through the inductor, but only in T ON through the AH transistor. This means that the average current is
The relationship between line and phase currents refers to how the current flowing in the lines connecting power sources to loads differs from the current flowing through individual components or phases in a multi-phase system. This distinction is essential in understanding the behavior of electrical circuits, particularly in delta and wye
Power is voltage X current, therefore battery voltage X battery current = "phase voltage" X phase current. Battery voltage and battery current are fairly easy to measure. "Phase voltage" is roughly proportional to the motor speed (and so is the controller''s PWM).
Motor current in each phase line approximates a bipolar ''square'' wave with a duty cycle of 2/3, 1/3 flowing at full supply voltage and the other 1/3 while voltage is ramping down to zero. From this information it should be possible to calculate the rms current.
When you are accelerating at a constant torque you will see linear increase in power and therefore in battery current. What are phase amps exactly? They''re talking about a motor that has 3 phases which are three electromagnets. There is

Determine the phase current if the line current in a delta system is 20 amperes: Given: IP (A) = 20A. Line current, I L(A) = IP (A) * 1.732. IP (A) = I L(A) / 1.732. IP (A) = 20 / 1.732. IP (A) = 11.54A. Line Current, Line Voltage, Phase Current and Phase Voltage – Three Phase Circuits. Previous article Motor Start-Up Current Calculator, Formula, Motor Start-Up Calculation. Next
Phase/Battery current ratio. Most common controllers allow the owner to adjust the motor-phase / battery amps current ratio. If you don''t know what that is, the motor-phase current can be set a little higher than the battery current, and 1.5:1 seems to be pretty common. From madin88, in Austria: "High phase amps = good acceleration from zero to mid speed
Line & Phase Current and Line & Phase Voltage in Delta (Δ) Connection. The current of Line 1 can be found by determining the vector difference between IR and IB and we can do that by increasing the IB Vector in reverse, so that, IR
The current leaves the battery and goes through one of the mosfets through one one phases and then through the other phase and back to the negative terminal of the battery. Current in a circuit cant be higher at one point than another point, unless it splits.
But in a delta connection, line current is √3 times phase current. Both cases use the formula S = √3 × Vline × Iline for total power. For example, a star connection with a phase voltage of 400 V and a phase current of 10 A
From this. You can have low phase voltage but high phase current be equal to steady battery voltage and low battery current. Phase voltage is also proportional to motor rpm, so low at low rpm and equal to battery at full speed assuming it''s motor limited. A lot of simplifications here. But it''s how you can have phase current =/= battery
Phase current "squared" makes heat in the motor. So, you will quickly overheat with high phase currents [that are above saturation] for only a modest improvement in torque, because the square grows so fast. The battery
Phase current "squared" makes heat in the motor. So, you will quickly overheat with high phase currents [that are above saturation] for only a modest improvement in torque, because the square grows so fast. The battery current determines the max power, and should be set for battery, BMS, and wiring capacity (or less).
By "line" you mean the AC line. by "phase" you mean 1 phase of a multi-phase line. Line voltage is the voltage seen on the AC line, typically single phase. Line current is the current that results when that voltage is applied to a load. If you have a 3 phase line, then each of the 3 phases (a separate wire) has it''s own voltage, phase
The relationship between line and phase currents refers to how the current flowing in the lines connecting power sources to loads differs from the current flowing through individual components or phases in a multi-phase system.
The current that passes through every line is known as the line current. The line current in a delta connection is √3 times the phase current, although the phase and line voltages are the same. The line and phase currents in a star connection are equal, but the line voltage is approximately three times the phase voltage.
Phase current is important because it makes heat in the motor, and high phase currents above saturation can quickly lead to overheating for only a modest improvement in torque due to the square relationship between heat production and current. The battery current determines the max power and should be set for the battery, BMS, and wiring capacity (or less). Phase current squared makes heat in the motor.
Line Voltage Equals Phase Voltage: The line current in a Delta connection is √3 times the phase current, while the line voltage is equal to the phase voltage. This characteristic makes the Delta configuration appropriate for systems that need a large current capacity at a constant voltage.
Therefore, current in a line conductor is the same as that in the phase to which the line conductor is connected. For a balanced load, all the phase currents are equal in magnitude but displaced 120° from one another. Fig.
Phase current equals line current: In a Wye configuration the phase current equals the line current, but the line voltage is √3 times greater, allowing for power delivery at various voltage levels.
