Claim:
1. An electronic device to control a plurality of motor drive circuits to drive a multi-phase motor in a force assisted system, the electronic device comprising: a motor control circuit to generate control signals and to provide the generated control signals to the motor drive circuits, wherein the motor drive circuits being coupled to a supply voltage, each motor drive circuit selectively permitting current to flow into or out of a respective phase of the multi-phase motor connected to the motor drive circuit in response to being driven by respective control signals; and a fault processor to detect a fault condition causing a fault current in a first motor drive circuit and, in the event of the fault condition being detected, to generate an alternative control signal for at least one motor drive circuit of the plurality of motor drive circuits to permit a compensation current to flow, the compensation current to cause a force having a direction opposite to a faulty force due to the fault current.
