14 Electrical Characteristics of the Motor you should know

Electrical characteristics like voltage, frequency and phase of power supply should be consistent with the motor nameplate rating. A motor will operate satisfactorily on voltage within 10% of nameplate value, or frequency within 5%, or combined voltage and frequency variation not to exceed 10%.   1. Voltage Common 60 hz voltages for single-phase motors are …

Practical checks for motor selection on AC adjustable speed drive systems

   1. Determine motor enclosure requirements Most often the environment dictates the motor enclosure selection. However, in the case of all ventilated motors, care must be taken to provide space for adequate ventilation. Some examples of commonly available enclosures for non-hazardous locations are: Self-ventilated open dripproof (ODP) motors are not suited for environments containing significant amounts of …

3 Easy Steps to stop Bearing Current Failures with Drives

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 …

All your drive needs taken care of, for less than the price of a cup of coffee a day.

There are over 10,000,000 motors installed in the UK with over 50% of them controlled by variable speed drives, that percentage increase to a staggering 92% on critical drive applications. Today’s modern drives have on average over 1000 different parameters that can bet set by the user to exactly match your process. Modern drives have …

Eight practical applications of testing ground system using clamp-on tester.

Understanding the ground system First of all, it is extremely important that the operator/engineer understand the ground system that is being tested. The clamp-on measurement works well in many situations, but it has limitations and is not applicable in some configurations. Clamp-on ground testing is a relatively new method of determining the quality of a …

What happens when the problem goes beyond the drive application?

Last month we had a callout to a utility customer who had an ABB low harmonic 315kw VSD fail on short circuit failure, this was in the early hours of a Sunday morning and the failure was beyond an onsite repair due to the extent of the damage. So we were on site and installing a hire …

How to know if you set the correct current on a motor thermal overload relay

Start with full-load current… The full-load current at a given voltage indicated on the nameplate is normative for setting the overload relay. Because of the variable voltages around the world, motors for pumps are made to be used at both 50 Hz and 60 Hz in a wide voltage range. Therefore, a current range is …
