Linear Voice Coil Motors

Linear DC Motors, Voice Coil Motors (VCM) or Voice Coil Actuators (VCA) are the simplest type of electric motors. These motors consist of two separate parts; the magnetic housing and the coil.

Applying a voltage across the terminals of the motor causes the motor to move to one direction. Reversing the polarity of the applied voltage will move the motor to the opposite direction. The generated force is proportional to the current that flows through the motor coil. This force is almost constant in the specified stroke range of the motor.

Voice coil motors do not need commutation and using a position sensor, positioning accuracies of less than one micron or 0.00004 inches are achievable.

The non-commutated motor construction increases reliability. The direct coupling of the motor to the load allows for fast acceleration / deceleration and high speed operation.

Very high speeds and accelerations can be easily achieved.

The moving part needs to be supported by a mechanism supplied by the customer.

This type of motor may be used in conjunction with a position sensor and a motion controller for accurate positioning.

The other applications of the voice coil motors are force and pressure control.

All the following motors can be manufactured with metric threads in production quantities.

Mounting hardware in various lengths and styles is available and may be obtained at
