Mar 09, 2016 The only suitable method to operate an induction motor with variable speed at higher load torque is VFD variable frequency drive. DC or universal motors can be easily speed controlled versus motor voltage, e.g. using a triac or SCR controller. Thats why they have been preferred for washing machines and other home appliances for many years.

Mar 25, 2007 If the ball mill will always operate at a fixed speed, the VSD is an expensive option. One major disadvantage of using a VSD or a fuid coupling, is that there is an additional 5 loss all the time that the ball mill is operating. The soft starter has only about 0.5 loss and a much longer expected life.
The Chinaware ball mill can realize automatic control and can switch between the variable speed drive and mains supply. Through the VFD drives automatic voltage adjustment function, the motor can achieve its highest efficiency. Starting current is only 15 of the previous, realizing soft start.
