FIGURE 1: This electrical schematic diagram shows the cooler’s single-phase, R-134a capacitor start/capacitor run (CSCR) refrigeration compressor motor, and starting relay circuit section. July 6, ...

One of the more popular three-phase electrical services supplied to medium-size commercial buildings is the Wye or Star configuration transformer. The name comes from the transformer’s secondary ...

Bearing-related problems are among the most common causes of motor failures. Solving those problems will reduce motor failures. Did you know bearing-related problems cause more than half of all motor ...

The operation of an electric motor is typically simple and reliable, making it possible to overlook during day-to-day maintenance practices. Having a checklist makes it easy to know exactly what to ...

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 ...

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 ...

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 ...

Every day engineers design products that employ single-phase induction motors. Speed control of single-phase induction motors is desirable in most motor control applications since it not only provides ...
