Absolute vs Incremental Encoders

Industrial AC motors typically utilize either an optical absolute encoder, an optical incremental encoder, or a resolver. In this article, we will focus on the primary differences between absolute and incremental encoders. In many ways, the functionality of both optical encoders is very similar. An encoder sits directly on the backside of the motor shaft….

TEST EQUIPMENT FOR MOTOR EVALUATION

Here at Precision Zone, we use specialized test equipment for a full evaluation of motors and their performance. With these tools, we are able to obtain a complete analysis of the motor’s health.  With just a quality multimeter, a reduced test can be performed to try and identify any major issues with the motor’s windings….

Ballbar Testing

The absence of CNC maintenance and testing equipment can lead to bad parts being manufactured. The ballbar test, when appropriately set up, carefully monitors the location of sensors on the ballbar within a created XY plane. Once it has been set up, executing a circular interpolation allows the device to accurately record how smooth or…

Electric Motor Housing Repair

Over time, bearing housings on a motor can wear down and cause extra friction with the bearings. As this gets worse, it allows extra play for the bearings where there normally should not be any free space. Once this occurs, that extra play in the rotation of the bearing can lead to some major issues….

Okuma MIV Series AC Spindle Drives

Series Overview This month, we dive deeper into one of the Okuma AC spindle series we often work on – the MIV inverter spindle series. This series offers a few different capacity variations, ranging anywhere from 1.0kW and going upwards of 45kW. A DC power supply is required, as shown below, to supply the MIV…

Improper Industrial Repair Practices

When it comes to electronic repairs, there are many routes and shortcuts that can be taken to get the unit back up and running. In some industries, this not be an issue, but when it comes to industrial electronics and manufacturing repairs, cutting corners will ultimately result in unsatisfactory outcomes for you and your company….

The Inverted Concept

As we go about our daily business, few may stop to admire the simple technology behind the inverter drives that run our machines. The concept is simple and the implementation has become more efficient over the years. Where older units were larger, heavier and relatively basic in their implementation, newer models are slim, sleek and…
