A method of operating a brushless motor having a stationary assembly with at least two different energizable windings for producing spaced apart magnetic fields in time sequence, and a rotor adapted to rotate in response to the magnetic fields, the method comprising the steps of: simulating rotor position in accordance with the back emf condition of at least one winding; selectively energizing the windings in accordance with the simulated rotor position; sensing an underspeed condition when the motor speed is less than a minimum value for a length of time; and preventing energization of any of the windings when the motor speed is less than the minimum value for the length of time. A method of operating a brushless motor having a stationary assembly with at least two windings energizable from a voltage source for producing spaced apart magnetic fields in time sequence, and a rotor adapted to rotate in response to the magnetic fields, the method comprising the steps of: simulating rotor position in accordance with the back emf condition of at least one winding; selectively energizing the windings from the voltage source in accordance with the simulated rotor position; sensing an undervoltage condition when the voltage source provides a voltage that is less than a minimum value; and preventing energization of any of the windings when the undervoltage condition is sensed. A method of operating a brushless motor having a stationary assembly with at least two windings and energizable from a voltage source for producing spaced apart magnetic fields in time sequence, and a rotor adapted to rotate in response to the magnetic fields, the method comprising the steps of: determining the back emf condition of at least one winding; simulating rotor position in accordance with the determining back emf condition of said at least one winding; selectively energizing the windings with a voltage from the voltage source in accordance with the simulated rotor position as defined by the determined back emf; sensing an overvoltage condition when the voltage is greater than a maximum value; and preventing energization of any of the windings when the overvoltage condition is sensed. A control system for a brushless motor for energization from a voltage source for the motor, the motor having a stator with windings and a rotor mounted for rotation relative to the stator, comprising: a circuit for generating an input signal corresponding to the presence of the rotor at one of a plurality of predetermined rotary positions with respect to the stator; electrically controllable switches connected to the windings to control the flow of current therethrough; an electronic control responsive to the input signal for controlling in a closed loop running mode the switches to commutate the windings of the motor after receipt of the input signal, said electronic control also being responsive to the speed of the motor, and operative to start the motor in a starting mode by controlling the switches to commutate the windings at an increasing rate, and then to shift commutation to the running mode once the motor reaches a predetermined speed, said electronic control being operative to determine the commutation rate as a function of the voltage applied to the motor.
