FAQ For 4mm Coreless Motor

What makes LCM0408 coreless motors different from other types of motors?

Answer: Coreless motors lack an iron core in the armature, which reduces the mass of the roto. It allows for faster acceleration and deceleration.

Are coreless motors suitable for high-precision applications?

Answer: Coreless motors can achieve high speed and precision, but they may not be suitable for high precision applications that require low torque ripple or absolute position control.

Can coreless motors be used in wet environments?

Answer: Some coreless motors may be equipped with waterproof coatings and seals, but typically coreless motors are not designed for use in wet environments.
