H2W (Santa Clarita, CA) introduces a new DC Linear Brush-Type Servo Amplifier (LCAM 5/15) that is ideally suited to drive our complete line of voice coil linear actuators. Linear amplifiers allow the current to flow continuously to the motor which prevents any dead-band issues that occur in many PWM type amplifiers. Additionally, linear amplifiers have low EMI, and no audible noise that also can be found in many PWM type amplifiers. Therefore because of their high current loop bandwidth, coupled with a low EMI, this leads to a smooth motion profile, which makes linear amplifiers the best choice for high precision applications.
