摘要： A system in which the operation of an electric motor is controlled by electronically controlled switches. The system includes the motor having a run winding and a start winding, a heating component, and a motor control subsystem. A control unit closes a first switch to energize the run winding, closes a second switch to energize the start winding, determines based on an amplitude and a lag time of a current flowing through the motor whether the motor has started and is running normally, and if so, opens the second switch to de-energize the start winding and closes a third switch to activate the heating component. The control unit determines whether the motor has started and is running normally by comparing the real time amplitude and lag time of the current to a plurality of stored amplitudes and lag times associated with different operating conditions.

摘要： An antenna assembly comprises a substrate, an impedance matching network, and a driven antenna element. The substrate includes an insulating layer and a first electrically conductive layer disposed on a top surface of the insulating layer. The impedance matching network includes a balun, a first resistor, and a second resistor. The balun converts unbalanced signals to balanced signals and vice-versa. The first and second resistors are electrically connected to the balun. The driven antenna element is formed from the first electrically conductive layer and disposed on the top surface of the insulating layer. The driven antenna element includes a body, a first arm, and a second arm with the first and second arms spaced apart from another, parallel to one another, and physically connected to opposing ends of the body. The first arm is electrically connected to the first resistor. The second arm is electrically connected to the second resistor.

摘要： A system for wirelessly programming and diagnosing a motor includes a server computer system, a portable electronic device, and a wireless communication device. The server computer system stores motor operating parameters and other motor data that can be accessed by the portable electronic device over a wireless communication network for identifying a suitable replacement motor for an unserviceable motor. The server computer system also generates motor programming instructions for programming the replacement motor to emulate the unserviceable motor. The portable electronic device wirelessly transmits the motor programming instructions to the wireless communication device for storing the motor programming instructions on a memory of a controller of the replacement motor so that the replacement motor will emulate the unserviceable motor.

摘要： Various embodiments of an electric motor and electronic control for an electric motor are disclosed. An exemplary electric motor comprises a single-phase brushless permanent magnet electric motor. In exemplary embodiments, the electronic motor control is configured to commutate an electric motor at a frequency other than line frequency, perform pulse width modulation, and drive the electric motor with a drive waveform that approximates the counter-electromotive force of the motor.

The power supply may receive a first input voltage and lower the first input voltage to a second lower voltage. The fan motor is electrically coupled to be driven by the first input voltage and the motor control is electrically coupled to operate using the second lower voltage from the power supply. The motor control may include a microcontroller, level shifters electrically coupled to the microcontroller, and drivers electrically coupled to the level shifters and configured to drive the fan motor.

摘要： A drying device has been developed having a single electric motor configured to drive a drum and directly drive an air blower. The single electric motor is a non-line frequency electric motor. The drum is coupled to a support frame to enable rotation of the drum relative the support frame. The drum has an interior space for holding a load of articles, such as clothing. The motor includes a controller configured to regulate the angular velocity of the output shaft of the motor with reference to the current drawn by the motor.
