How can I stop Bearing Current Failures?

How to deal with persistent bearing currents On rare occasions, operators in the process industry may note that their low voltage motors experience a current flowing through the motor bearings, especially when they are used with a variable speed drive (VSD). Left unchecked, these bearing currents will inevitably result in premature failure. Two new approaches can eliminate …

Variable Speed Drive Applications

Probably the first question that should be asked is what type of application you are considering for a VSD. There are basically three types: constant torque, variable torque and constant kW applications. It must be pointed out that constant and variable torque loads are the dominate two types of applications. A constant torque load is …

When to use a Soft Start versus a Variable Speed Drive

A soft starter is, as you would expect, a device which ensures a soft starting of a motor. A Soft Start has different characteristics to the other starting methods. It has thyristors in the main circuit, and the motor voltage is regulated with a printed circuit board. The softstarter makes use of the fact that …
