20140271280 | PUMP MOTOR - An electric pump motor is provided. The motor includes a stator assembly including a magnetic stator component and an overmolded stator casing sealingly encapsulating the magnetic stator component. A rotor assembly that is rotatable about an axis includes a rotor shaft extending along the axis, a magnetic rotor component, and an overmolded rotor casing fixedly interconnecting the rotor shaft and magnetic rotor component. The rotor shaft is connected to an impeller that imparts a thrust load on the rotor shaft. The rotor and stator assemblies are configured so that the magnetic components induce a solenoid force on the rotor shaft opposite the thrust load. | 09-18-2014 |
20140265984 | System For Selecting An Output Speed For An Electric Motor - An electric motor has a control circuit that enables an operational speed of the electric motor to be selected with reference to multiple ranges of speeds and the input voltage to the motor. Switching between speed ranges occurs in response to activation of a switch or in response to expiration of a time period set by a selector switch. | 09-18-2014 |
20120234856 | MULTIFUNCTION PMDC MOTOR APPARATUS AND METHOD THEREOF - A control circuit for a PMDC motor used in an ice delivery apparatus, the circuit including a double pole double throw relay that switches both sides of the circuit and peripheral circuitry connected between a power source and the double pole double throw relay to rectify the power source and power the PMDC motor. | 09-20-2012 |
