Publisher Summary This chapter gives a thorough review of electric motors. Electric motors are the most common source of motive power for machine trains. As a result, more of them are evaluated using microprocessor-based vibration monitoring systems than any other driver. The vibration frequencies are monitored to evaluate operating conditions.

Transformers and electrical motors
2018Electric motors and transformers can be found in applications from computer disk drives, appliances, cars, power supplies, laptop and cell phone chargers, to industrial process lines, pumping systems, conveyers, escalators, and many more. For example, modern building services are heavily reliant upon electrical motors and drives, found in air ...

The history of spherical motors is traced, beginning with the initial research in the mid-1950s. Interest grew in the 1960s in their use in space, due to their light weight compared with that of conventional motors. In the 1970s, the spherical concept was applied to pumps where the impeller is of spherical shape so that no shaft seals are required. The
