2-Axis Motor Controllers

For 24V Military Vehicles

This series of 2-axis, digital motor controllers is designed to provide torque, velocity and position loop closure to drive brushless motors for use in military vehicle applications. The controller accepts 24VDC vehicle input power and command signals from any fire control system, in either digital or analog format, and interfaces with a control handle. There are three controller models available (MC100D, MC500D, MC1000D) that provide a range of output current from 80Apk/axis up to 800Apk/axis. A variety of communication interfaces are available, see common specifications on page 2. These controllers offer end user loop tuning to provide maximum torque and velocity loop closure and they interface with both resolvers and encoders for motor commutation. The advanced space vector algorithms optimize performance for new or existing motors to provide superior power densities. Typical applications are for use with gun turrets but all of these controllers can be customized as required. There are a wide range of end user programmable software features, as listed below.

MC100D

The smallest controller in the family the MC100D can output 80Apk/axis in a compact, lightweight package. This controller has an internal tilt/accelerometer sensor for improved stabilization performance.

MC500D

This MC500D is the mid-range model. It is available in 2 packages: the standard finned which can output 300Apk/axis or a cold plate mount which can output 400Apk/axis. The finned model has 4 sets of holes predrilled for use with isolation mounts.

MC1000D

The MC1000D is the highest output model at 800Apk/axis. The sides of the controller are predrilled for use with mounting brackets. Lifting handles (2) can be added if required. See picture of an MC1000D model with lifting handles and isolation mounts (back cover).
