TOKYO--(BUSINESS WIRE)--Toshiba Electronic Devices & Storage Corporation ("Toshiba") today announced the launch of “TB67B000AHG,” a new three-phase brushless motor driver for home appliances such as ...

Speed control of an AC motor requires a three phase supply that can vary both voltage and frequency. Such a supply creates a variable speed rotating field in the stator that allows the rotor to spin ...

Pulse width modulation is a form of signal communication that transposes a signal from analog to digital form. Analog signals with changing amplitude and frequency pass through a comparator and are ...

The MTD6501D is a three-phase full-wave driver designed for brushless sensorless DC motors. It has 180° sinusoidal drive, high torque output, and silent drive. It is intended to cover a wide range of ...

Bipolar stepper motors are used in many applications, from driving paper through a printer to moving an XY stage in industrial equipment. Typically, the motors are driven and controlled by inexpensive ...

Variable speed drives (VSDs), sometimes also known as variable frequency drives, are electronic devices used to regulate the speed of an ac induction motor. Electric motors consume approximately 25% ...

This article describes a simple technique for using a processors PWM output to produce an analog control voltage that matches the load’s input range, thus maximizing control resolution. Most ...

Pulse Width Modulation (PWM) or Pulse Duration Modulation (PDM) is a technique of converting analog signals into rectangular waveforms. The width of the waveform varies in proportion with the ...

In troubleshooting situations involving a motor, more than half the battle is simply isolating the problem. Whenever there’s a working motor, there’s a load and there’s some sort of motor controller, ...
