ABSTRACT:
Method of operating an electronically commutated motor, controlled by a board mounted electronic circuit, wherein current surges in such circuit are suppressed while dissipating heat associated with such suppression from motor structure as opposed to the control circuit. The heat associated with control circuit current surge suppression is dissipated into the bowels of the motor as opposed to being dissipated from a heat generating resistor mounted on the control circuit board as has been done heretofore. Illustrated structure includes current surge suppressing special winding turns on the motor core. Such special winding turns are connected with a known electronic control circuit so that power supplied to such circuit is transmitted through the special winding on the motor. Current surges associated with operation of the motor control circuit are then suppressed, during operation, by the special winding inside the motor.
