noun
permanent magnet synchronous motor; PMSM
Technical term in electrical engineering. Often abbreviated as PMSM. A type of brushless electric motor where the rotor contains permanent magnets and rotates synchronously with the stator's magnetic field.
この電気自動車には永久磁石同期電動機が搭載されている。
This electric vehicle is equipped with a permanent magnet synchronous motor.
永久磁石同期電動機は高効率で知られている。
Permanent magnet synchronous motors are known for their high efficiency.
An induction motor, which uses electromagnetic induction rather than permanent magnets. Less efficient but simpler and more robust.
A broader category of brushless motors; PMSM is a specific type with sinusoidal back-EMF, while BLDC often refers to trapezoidal back-EMF motors.
Compound of 永久磁石 (permanent magnet), 同期 (synchronous), and 電動機 (electric motor). A direct calque of the English term.
