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 ...

As an electric motor’s rotor turns in close proximity to the motor windings, a bucking voltage or back electromotive force (EMF) is generated. The back EMF (BEMF) generated across the start winding is ...

For safe, long-term use of a compressor, the motor winding temperature must be kept below certain limits, in all conditions in which the appliance may operate. For example, compressors from AC ...

Two-parameter motor models assume that the entire motor exhibits one dynamic temperature. Four-parameter thermal models are just as easy to use, but far more accurate — and better for calculating ...

Over on his YouTube channel our hacker [Yuchi] is building an STM32 BLDC motor winding machine. This machine is for winding brushless motors because manual winding is highly labor intensive. The ...

Single-phase and 3-phase AC squirrel cage induction motors need some type of control circuit to initiate a start or stop function. The two types of ladder control circuits commonly used are the 2-wire ...

Combined with productivity and associated reliability costs, a motor circuit analysis program can justify itself immediately. In recent years methods for controlling energy costs have evolved from a ...

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 ...

Full-voltage, single-speed motor starters: Single-speed squirrel-cage motors have starters that fall into two categories: full-voltage or across-the-line starters; and reduced-voltage starters.

Swedish boutique super/hyper/mega-car manufacturer Koenigsegg is at it again, adding to the automotive technology lexicon with its new Dark Matter "Raxial Flux" electric motor, boasting full ...

This article describes the testing results following routine performance assessment of an electrical motor both in its original state and after rebuilding it using products made by Zeus, such as the ...
