The schematic of a PMSM drive using a DTC-based speed loop PDFF controller is shown in Fig. 1. This DTC scheme is implemented in stator flux frame, which requires knowledge of stator flux in ...

I recently ran into an interesting dilemma while running tests on TI’s new InstaSPIN™-FOC sensorless motor control software. “How do you define motor torque?” On the surface, this sounds like an easy ...

Electric clutches may not be always the engineer’s first choice when looking at torque-control solutions. Electric motor drive systems, pneumatic clutches, or even friction spring types are thought of ...

Speed, torque, and horsepower are three inter-related parameters in motor control. The speed of a motor, measured in revolutions per minute (rpm), defines a motor's ability to spin at a rate per unit ...

A dynamometer is a testing device that helps engineers collect data for various mechanical loading conditions that a motor or engine might encounter in a particular application. Other than testing the ...

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 ...

Most known for their versatility, electric motors have revolutionised the way we view the core definition of power, qualifying it as effective energy expenditure concerning work done over time. Among ...

I do a lot of new car testing at the racetrack, and the more at-the-limit testing I do, the more I’ve come to realize that “Off” rarely means 100 percent off when it comes to electronic stability ...

TOKYO, Oct 20, 2022 - (JCN Newswire) - Hitachi Astemo, Ltd. has developed a prototype of an anti-jerk control that improves ride comfort by reducing the back-and-forth jerk* that occurs when the ...
