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.

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 ...

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 ...

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 ...

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 ...

Build in a thermal safety margin to handle servomotors that heat up more than theoretical models predict when the torque cranks up. • The relationship between intermittent and continuous torque is ...
