Electric vehicles use motors powered by batteries and include components like inverters and reducers. Permanent magnet synchronous motors are favored in electric vehicles for their efficiency and torque benefits, as they do not experience slip and provide high torque from the start.
Insights
- Electric vehicles utilize Permanent Magnet Synchronous Motors (PMSM) for efficiency and torque advantages, as these motors do not experience slip, ensuring high torque from the beginning through magnetic force regulation.
- The rotation of electric vehicle motors is influenced by induced current, which can cause rotation without direct current supply, highlighting the intricate relationship between current flow and magnetic fields in driving the vehicle's components.

Electric Vehicle Motors: Power and Efficiency
- Electric vehicles are powered by a battery and motor, with the module containing an inverter, motor, and reducer.
- The motor of an electric vehicle rotates due to current creating a magnetic field around a wire.
- Induced current occurs when a magnet is moved around a coil, causing rotation.
- The rotation of a metal rod into a disk shape is influenced by a magnet, inducing current and rotation.
- Current must be supplied to turn the motor, but induced current can also cause rotation without direct current supply.
- The direction of force that rotates the disk is determined by Fleming's right-hand rule and the planning left-hand rule.
- Slip occurs when the disk rotates slower than the magnet, generating electromotive force.
- An induction motor rotates due to a rotating magnetic field created by a coil and a magnet.
- Permanent magnet synchronous motors (PMSM) are used in electric vehicles for efficiency and torque benefits.
- PMSM motors do not experience slip, providing high torque from the start due to magnetic force control.
