Certain components of motors degrade with time and operating stress. Electrical insulation weakens over time with exposure to voltage unbalance, over and under-voltage, voltage disturbances, and ...

Growth of coiled tubing workover operations during the past decade has increased the demand for improved downhole motors for use in cleanout and milling operations. To meet that demand, engineers have ...

Frequently, when it comes to step motor selection, users will select a motor with the highest holding torque rating, assuming that it will give them optimal performance. However, it is an improper ...

Motors often fail without warning and when they do the primary concern is getting the affected systems up and running as quickly as possible. If a replacement is readily available, the failed motor is ...

Recent studies indicate the level of knowledge and implementation of motor system energy-efficiency measures is low. A plethora of information on motor system design, best practices, purchasing, and ...

The amount of noise in a motor depends on the type of motor, environmental conditions, and the specific application. Permanent magnet and hybrid stepper motors are generally quieter, as they have a ...

To better understand the origins of noise, we need to think about how the rotation movement takes place. When a stepper motor performs a step, it does not stop immediately but continues to move ...

The motor calculations presented here apply to changing conditions of a blower motor when pulley adjustments are made. However, these calculations are useful wherever electric motors are used. These ...

This file type includes high resolution graphics and schematics when applicable. Determine if a VFD is right for your application. The primary function of a variable frequency drive is to vary the ...
