The main difference between electromagnetic actuators and piezoelectric actuators lies in their driving frequencies.

Electromagnetic actuators operate at a single frequency, typically below 500 Hz, whereas piezoelectric actuators can be driven across a wide range of frequencies, from low (1 Hz) to high (up to 40 kHz).

TAIYO YUDEN’s piezoelectric actuators offer a range of driving frequencies tailored to different applications.
