Magnets in the Voice Coil Motor (VCM) A voice coil motor (VCM) is a special form of direct-drive motor. Its working principle is that the energized coil (conductor) will generate force when placed in a magnetic field, and the magnitude of the force is proportional to the current applied to the coil. The motion form of the

Everything You Need to Know About Voice Coil Motors
Everything You Need to Know About Voice Coil Motors Voice Coil Motors (VCMs) are the simplest type of electric motors, which consist of two separate parts: the magnetic housing and the coil. Voice coil motors are brushless and do not utilize commutation. Their structural stability can support high positioning resolutions presented by external position sensors
