Abstract
An integrated controller for an operator unit for powering an overhead garage roller door or roller shutter is described. The operator unit comprises a motor, an output drive assembly, a timing assembly unit, and a clutch assembly for providing selective engagement between motor powered operation and manual operation (provided by a chain rotating a chain wheel). The motor is arranged to drive a shaft which, in turn, provides drive to the roller door or shutter assembly (not shown), which includes an axle around which the roller door or shutter is wound. The integrated controller comprises an inverter for receiving a single phase power supply and supplying three phase power to drive the motor; and a drive controller in operable association with the inverter for providing active management of the operation of the motor.
