July 7, 2020 -- H2W introduced a DC Linear Brush-Type Servo Amplifier (LCAM 5/15) that is designed to drive the 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. They are often used in precision stages to drive linear motors or voice coil actuators in semiconductor, medical, and optical equipment, since most voice coil actuators have very low inductance windings (less than 1 mH), this makes a linear servo amplifier the preferred method to drive voice coils.
Amplifiers will be preset to match the continuous and peak current specifications of any H2W voice coil motor.
