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 ...

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 ...

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.

HIOKI recently announced the launch of the Impulse Winding Tester ST4030, which is the company’s first instrument to provide functionality for testing for defects in motor windings. HIOKI provides a ...

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 ...

SAIC Motor has been granted a patent for an innovative electric motor winding structure. This design features a multi-phase winding arrangement using hairpin conductors in a grooved iron core, ...

Designers can squeeze down the size and cost of small machines through the use of motors with built-in resolver functions. Donald Labriola, P.E. This 23-frame high-pole-count ac motor-resolver ...

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 ...

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 ...
