Brush-type motors are the time honored workhorses of industry world-wide. Price, size and torque considerations frequently outweigh the disadvantages of shorter maintenance intervals and limited speed. Choosing brush-type servo motors allows the greatest selection for the least cost.

Linear Amplifiers

A high performance linear servo amplifier is customarily utilitzed when amplifier power dissipation can be tolerated, but motor heating or electrical or RF noise cannot, or when low-inductance loades are employed. We provide these lines of linear amplifiers:

LDH-A2 Series A medium power linear servo amplifier with American-style packaging.

LDU-S1 Series A low power linear servo amplifier with 3U Eurocard (VME) form factor packaging.

Pulse Width Modulation (PWM) Amplifiers

Pulse width modulation (PWM) has traditionally been utilized to reduce amplifier power dissipation, at the expense of performance. Our advanced design pushes the limits of the PWM performance envelope toward that of linear amplifiers while retaining the efficiency of PWM.

PAU-Sx Series A high power PWM servo amplifier with 6U Eurocard (VME) form factor packaging.

PDH-Sx Series A medium power PWM servo amplifier with American-style packaging.

XPA-S1 Series A medium power PWM servo amplifier enclosed in a 3E Edge Mount package.

PDU-S1 Series A medium power PWM servo amplifier with 3U Eurocard (VME) form factor packaging.
