MC40 2-Axis Brushless Motor Controller

This series of digital militarized high voltage, 2-Axis, Brushless Motor Controllers is designed to provide torque, velocity and position loop closure. The controller accepts command signals from any fire control system (FCS) in either digital or analog format, and interfaces with a control handle. The advanced space vector algorithms provide optimum performance for new or existing motors to provide outstanding power densities. There is also an IGBT (InsulatedGate Bipolar Transistor) and resistor shunt regulator circuit to control regenerative energy if required. Additionally, there are a wide range of end user programmable software features, as listed below.
