Voice coil motor

This type of motor is supplied without internal linear bearings and shaft. A customer supplied linear bearing is required to support . Reversing the polarity of the . These non-commutated electromagnet devices are used in linear and rotary motion applications that require . They are available in both moving coil and moving magnet designs, and have the longest operational life of our VCAs.

A fully housed voice coil actuator (VCA) further expands upon the idea of the semi-housed VCA, incorporating the self-aligning bushings and shaft, but fully captures the coil assembly to keep it concentric with the field assembly, adds an internal flex circuit to protect external moving wires and also limits the axial travel on .

Geeplus Europe specialist in voice coil motor design and manufacturing.

The voice coil motor keeps track on the pulse-wave width and . Voice Coil Motor Characteristics. Rotary voice coil actuators (VCA) are ideal for high acceleration applications that require angular movement. This system includes optional air cooling that would allow the stage to achieve higher continuous . Drawing quick view Mechanical Drawing . Infinity Series ironless (air core) linear motors and linear voice coil motors.

The question of whether to use voice coil actuators or solenoids for small displacement motion control applications comes up often. This article explains the key differences between each product and why you might choose one over the other for your application. Terminal Voltage, Vdc, 4 120. Open and Short-Circuit Detection on VCM Pins. The DRV2device is an advanced voice coil motor.

Undervoltage Lockout (UVLO) driver for camera auto focus. Thermal Shutdown converter for setting the VCM current. A desired frequency and amplitude is set i. The driver incorporates surface mount technology to achieve an exceptional power density.

This driver does not accept any type of feedback. Its operating voltage range is 2. V, and its maximum output current is 1mA .
