Is the Standard International (SI) unit of electric potential or electromotive force. Voltage can be expressed as an average value over a given time interval, as an instantaneous value at a specific moment in time, or as an effective or root-mean-square (rms) value.

Voice Coil Actuator

Direct-drive limited motion devices that use a permanent magnetic field and coil winding to produce a force proportional to the current applied to the coil. These Electromagnetic devices are used in linear and rotary motion applications requiring linear force or torque output, and high-acceleration, or high-frequency actuation.
