High power low RPM D.C. motor
InactiveUS6037692AIncrease motor powerHigh strengthAC motor controlAsynchronous induction motorsEngineeringConductor Coil
A high power low RPM direct current electric motor is disclosed whereby the high power output is achieved in one of two ways or both. In the first case, the need for cooling is reduced simultaneously along with an increase in the utilization of the magnetic field present in the motor permanent magnets. This is achieved by wrapping the electromagnet core with windings that are capable of demagnetizing the rotor permanent magnets under stall conditions. Interlocking motor circuitry is provided which prevents the full activation of these motor windings until motor RPM values reach a safe level. This increases motor power while decreasing resistive losses in electromagnet windings. In the second case, the rotary portion consists of a large diameter relatively flat rotor containing permanent magnets and having built in vanes for moving air over the electromagnet stator windings providing forced air cooling.

An evaporative emission control system detects an opening failure of a purge control valve that controls the amount of purge gas flowing from a canister into an intake passage of the engine, and determines whether a significant shift occurs in an air / fuel ratio feedback factor when the opening failure is detected. If the air / fuel ratio feedback factor is shifted to the rich side, a rich-side initial value is set to a vapor concentration learned value, and, if the feedback factor is shifted to the lean side, a lean-side initial value is set to the vapor concentration learned value. These initial values give larger changes to the vapor concentration learned value than update amounts by which the learned value is updated during normal learning control.
