The digital variable reluctance (DVR) smart motor is a switch reluctance motor that can be used in place of ac or dc motors for certain manufacturing and building maintenance applications. The motor has no brushes, permanent magnets or electrical connection to moving parts and no current flow in the rotor. It can turn off and on with no power spike, providing a low-voltage start. A microprocessor can save and store speed information on different settings and switch from one to another immediately. The smart technology also can detect the input power source, allowing the motor to operate at 100 to 240 V.
