Non-Comm DC Voice Coil Linear Actuator ,a linear motor,product,NCC20-18-020-1X
Non-Comm DC Voice Coil Linear Actuator , NCC20-18-020-1X
This moving coil actuator (NCC20-18-020-1X) comes supplied with an aluminum bobbin in order to prevent eddy currents from being generated in the bobbin, and allow for a minimal resistance to the desired motion. This actuator also comes supplied with a thru hole, should your application require a hollow actuator.

Moving coil actuators do not come with a bearing system, if you would like to see actuators with a built-in bearing system please look at our moving magnet models. Or if you would like to see how we have integrated our voice coils into linear motion stages.

To determine your motion profile needs, use our linear motion calculator.

This motor has been integrated into the following positioning stages:
