An electric motor is a device used to transform electrical energy from its work form into its mechanical form and vice versa. High power and torque from an electric motor could be sent to the transmission or differential and then used for vehicle propulsion . Electric vehicles (EVs) may not need transmissions since the electric motor might potentially supply

Many battery-powered systems and Internet of Things (IoT) applications—such as smart meters, smart sanitation products, video doorbells, robotic toys, personal hygiene products, and electronic locks—contain a motor, solenoid, or relay.
The interaction between the battery and the motor physics produces some interesting design challenges, such as operating the system reliably as the battery voltage changes, minimizing standby power to increase system lifetime, and supplying large currents to the motor during startup and stall.
Large currents from motors create two problems in battery systems: they use energy unproductively, and they can cause the system to prematurely go into a low-battery lockout condition because of the voltage drop across R BAT. There are two main causes of large motor currents: inrush current during motor startup and stall current.
The DRV8210 and DRV8212 from Texas Instruments (TI) are examples of motor drivers designed for battery-powered applications with a supply rating of 1.65 V to 11 V. This accommodates the maximum voltage for a two-cell lithium battery stack (8.4 V) or an almost-discharged two-cell alkaline battery stack (1.65 V).
With four alkaline batteries connected in series, a motor driver with a 4.5-V minimum supply rating may disable itself using undervoltage lockout before the batteries fully drain.
