The two most important electric motors are the ac induction motor and the permanent magnet (PM) brushless synchronous motor, also known as the brushless dc or ac servo motor. These motors have ...

The power of a synchronous motor depends directly on the load angle: the greater the load angle, the more torque, which determines the power by the speed specified by the input gear and the ...

Three phase induction motors are commonly used is adjustable-speed drives and they have three-phase stator and rotor windings. The stator windings are supplied with balanced three-phase ac voltages, ...

Adjustable-frequency drives have been billed as an energy efficient way to drive three-phase ac induction motors. Nevertheless, designers should understand that motors fed by inverter power experience ...

October 2025 marks the 50th anniversary of the Low Voltage Variable Speed Drive (LV VSD), which was used in a commercial ...

Discover how 24V BLDC motors enhance HVAC efficiency and reduce maintenance costs. Learn key selection tips on torque, voltage, sizing, and system integration to ensure reliable, quiet, and ...

According to the United States Department of Energy, motors in homes and commercial buildings consume more than one-third of all the electricity used in these buildings. Sixty-five percent of ...

A compact wireless data acquisition system can investigate, monitor and optimise electric rotor motor operation, say Rolf Spellmeyer and Diego Llopis. In modern electric vehicles, different types of ...

Ordinarily, quadcopter drones have to tilt their front end downward when flying forward, increasing their frontal area and thus increasing drag. An experimental new drone gets around this problem, by ...

Tesla’s Model S is known for its long range, with the 100kWh version rated to travel 335 miles (540 km) between charges. On Tuesday, Tesla announced changes to the Model S drivetrain that boosted the ...
