Despite their advantages, ultrasonic piezomotors are not without limitations. The primary drawback is wear. The drive mechanism relies on friction, which inevitably leads to the degradation of the friction layer on the stator and rotor interface. This limits the lifespan of the motor compared to the near-frictionless operation of magnetic bearings or ball bearings.
Ultrasonic piezomotors offer several benefits over traditional motors, including: ultrasonic piezomotors
