Explosion Proof Electric Motors: Class, Groups & Divisions Explosion Proof Motors To understand what explosion-proof really means for electric motors, you need to be familiar with the two basic scenarios related to motor explosions. The first involves the surface...

New oil is always the best for your bearings, correct? Most new oil in a drum may not be as clean as you think, and you need to know why and what you can do about it. I always assumed that new oil was clean oil--until I started working with a customer who was having...

Prevent Electric Motor Failure with Predictive Maintenance Is predictive maintenance just a fad that’s trying to sell expensive, complicated equipment to production and manufacturing companies, or is it an effective maintenance paradigm? We know that motor failure,...

If motors are exposed to ambient vibration during storage, damage to bearings (such as false brinelling) can result. Ambient vibration can affect the motors when they are stored in close proximity to rail lines, production floors, and busy roads; if the motors cannot...

With the advances in technology around electric motor testing, the motor inductance testing is now easier to perform than ever. However, there are challenges that remain, and the most difficult issue lies in the lack of hard-set guidance from an independent body as to...

As part of its ongoing virtual seminar series, Hi-Speed Industrial Service recently hosted a virtual webinar on electric motor core testing, presented by Blake Parker, Director of Shop Operations. During the presentation, Blake reviewed factors that are critical to...

The vast majority of vibration analysis is performed using accelerometers that gather critical data for evaluating the condition of electromechanical equipment. Vibration data is often vital for troubleshooting and necessary for predictive maintenance. However, while...

Out of the blue, one of the key electric motors at your facility breaks down. That entire production line comes to a grinding halt (often literally, too). You have to quickly find where the spare motor is, get it ready to install and pull the failed motor. And when...

Here’s a statistic you should know: mechanical failure, rather than electrical failure, is the cause of 80% of failures in electric motors.  Unplanned failures cost facilities countless dollars each year due to the resulting loss of productivity, overtime repairs, and...

Electric Motor Reconditioning: Why and How Plant reliability has many facets, including the planned removal and reconditioning of critical electric motors and other electromechanical equipment. There are a host of benefits to reconditioning, but scheduled reconditions...
