Apparatus to exercise electrical motor drivers by electrically simulating a geared electric or electrical motor by providing an electronic load for the power signals that are applied to it. Current levels in the load are monitored in real-time using gate array logic and digital signal processing (DSP) algorithms to determine torque, acceleration, velocity and/or position data of the motor and gear train. Motor and gear train positional signals are generated and fed back to the motor driver device to close the servo loop. Control algorithms within the gate array and DSP accurately simulate the motor inertia and act to simulate a physical motor under varying load conditions. A control interface modifies critical motor parameters such as inertia, losses, gear ratio, and loading. |
