Understanding Variable Speed Drives (Part 1)

1999/03/01The motor's rotor position and speed is monitored in real time via a resolver or digital encoder to determine and control the motor's actual speed, torque, and power produced.

Grinding Mills

A magnetic clutch permits "floating" a synchronous motor on the line during mill shutdown to aid in power factor correction. The most compact direct drive, where electrical conditions permit its use, is the direct connection of a high torque synchronous motor (approximately 160% starting, 140% pull-in and 225% pull-out) to the pinionshaft through a flexible coupling (Drive 3).Get price

Coal Pulverizers

The main boiler was built as coal-fired, which is why pellets were ground in coal pulverizers that were slightly modified for biomass and operated at low temperatures to eliminate the risk of fire. Further modernizations and the addition of a fourth mill enabled that in 2014 the boiler was commissioned for wood pellets [76] .Get price
