Abstract
A portable service controller for controlling an electro-mechanical actuator, the portable service controller includes a battery configured to power the portable service controller and a user interface configured to receive input from a user and to responsively generate an input signal. The portable service controller also includes a phase sequencer configured to convert the input signal into a series of timed output signals and a driver circuit configured to convert the series of timed output signals into inverter gating signals. The portable service controller further includes a three-phase brushless motor inverter configured to convert inverter gating signals into control signals for a brushless motor of the electro-mechanical actuator. The portable service controller contains a motor brake on/off circuitry for engaging and disengaging the electro-mechanical actuator motor brake. The battery, the three-phase brushless motor inverter, the driver circuit, the phase sequencer and the user interface are all disposed in a housing.
