New Linear Voice Coil Motors with Internal Bearing by MotiCont

MotiCont has introduced three new models of linear Voice Coil Motors with Internal Bearing

This series features a small size body package; housing outside diameter is 0.625 inch, 15.9 mm. The range of the stroke of this series is from 0.125 inches (3.2 mm) through 0.50 inches (12.7 mm). The continuous force generated by this series is about 5.0 oz (1.4 N). The intermittent force at 10% duty cycle is about 6.0 oz (4.4 N).

The high performance voice coil motors are used in positioning applications where high speed, high acceleration or high accuracy is required. This series is integrated with an internal bearing that makes installation and usage much easier and faster.

The voice coil actuators are the simplest type of electric motors to operate. The non-commuted motor construction increases reliability with no cogging. The direct coupling of the motor to the load allows for fast acceleration / deceleration and high speed operation with zero backlash.

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.

The low moving mass also allows for high bandwidth servo loops. 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.

There are 15 models to choose from. All motors are available for immediate worldwide shipment.
