The dc linear brush-type servo amplifier (LCAM 5/15) is ideally suited to drive voice coil linear actuators. Linear amplifiers allow the current to flow continuously to the motor, which prevents any dead-band issues that can occur with PWM-type amplifiers. Additionally, linear amplifiers have low EMI and no audible noise. Their high current loop bandwidth, coupled with a low EMI, leads to a smooth motion profile, which makes linear amplifiers appropriate for high-precision applications. Amplifiers are preset to match the continuous and peak current specifications of any of the company’s voice coil motors.
