A brushless-DC motor is common in ceiling fan and pan-tilt-zoom (PTZ) camera designs. But you can’t use the same brushless-DC motor solution for both of these end products. A ceiling fan driver ...

Electric motors, which convert electrical energy into mechanical energy, play an essential role in a variety of industrial and robotics applications. Given that electric motors account for ...

The way we control the speed of fan motors or pump motors has tremendously changed in the past two decades with the introduction of variable-frequency drives (VFDs), aka variable-frequency controllers ...

The importance of DC electric motors in the automotive industry continues to grow, writes Matthew Beecham. The driving force behind market growth is motorists’ insatiable demand for safety, comfort, ...

Early incarnations of the electric motor first appeared in the 1740s through the work of Scottish Benedictine monk and scientist, Andrew Gordon. Other scientists such as Michael Faraday and Joseph ...

To control system operation, motors require a current measurement, which can be achieved using shunt resistors that provide a simple and cost-effective solution. Motors are used in countless consumer ...

DC Motors were king in industry up until the late 1980s; These motors were popular because they were able to run to a variable speed setpoint, and they could run at full torque from stall to base ...

Variable frequency drives (or VFDs) are widely used throughout industry to provide adjustable speed control of ac motors. Although modern versions are relatively simple to install and operate, VFDs ...

The driver is a key factor in determining a motor’s stall performance. Temperature can affect the stall torque of brushless DC motors. Tolerances on the motor parameters can significantly impact the ...
