Bearingless switched reluctance motors (BSRMs) represent a significant advancement in motor technology, integrating the functions of mechanical support and rotational drive within a single ...

Here are some answers to frequently asked questions about motor control. Motors provide the driving power in almost every stage of the manufacturing and production process. With this much productive ...

Motors account for at least half of the energy consumed in the U.S. Selecting the right control method for an application lets the motor run most efficiently while maximizing torque and overall ...

Read part 1 of this series on construction and operating principles here. Having understood the construction and basic operating principle of BLDC motor in the first part of this article, it becomes ...

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 ...

• Shaft twisting, mechanical flex, belt elasticity, and gear backlash are often culprits in speed-controlled systems that are unstable. • Sometimes a feedback device with a higher resolution can solve ...

The topic of motors and motor control techniques is wide and varied. Part one of this two-part article will cover the principles of alternating-current (AC) motor operation and control. Part two will ...

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 ...

Supplier Hitachi Astemo said it had developed a prototype of an anti-jerk control for EVs claimed to improve ride comfort by reducing the ‘back and forth jerk’ which occurs when the vehicle stops, and ...

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 ...
