摘要： A DC motor control for an electrical implement such as a reel mower includes a regulator having additional inputs connected to a main intelligent control which includes interlock circuitry. The additional inputs provide both an on/off or voltage select function and an interlock function. A low cost and low current field regulator circuit provides switching and load control and eliminates high inrush currents and voltage and current transients. On/off functions and level control functions can be provided from a logic level signal, and the motors can be started smoothly by bringing the voltage up gradually.

摘要： A differential steering and traction control system for an electrically propelled mower. Each of the front wheels has an electric motor wheel drive, and each rear wheel may have an electric steering motor. The operator's station has a steering wheel and a speed control. An electronic controller provides steering commands to the electric steering motor and separate speed commands to each electric motor wheel drive based on the angle of the rear wheel and the position of the speed control.

摘要： A rotor for a permanent magnet motor includes a rotor body and a plurality of permanent magnets carried by the rotor body. The rotor body has an outside rotor surface with a plurality of dovetail slots formed on the outside rotor surface. Each magnet is fit within one of the slots, protruding outward of the outside rotor surface in a radial direction. According to another embodiment, a rotor is provided having a rotor body that carries a plurality of magnets on its outside surface, and end caps that are fastened respectively to longitudinal ends of the rotor body. The end caps each have a angled rim surfaces that overhangs an end portion of the outer magnet surface of each of the magnets to retain the magnets onto the rotor body. The angled rim surfaces and the magnets can be configured such that by drawing the end caps tightly against the rotor body by use of fasteners, the magnets are wedged down onto the rotor body by the angled rim surfaces.
