Motor and drive system technology continues to advance throughout the industry. Oftentimes, this increased complexity presents a challenge to the teams who are making sure the equipment runs at peak ...

One of the more elusive causes of three-phase compressor motor overheating and failure is an imbalance in voltage. Compressor voltage unbalance can be found with a voltmeter by measuring between ...

Small and medium AC induction motors account for more than 75% of motor electrical energy demand; however, they typically receive less maintenance than their larger counterparts. This leaves them ...

Bob and Tim are at a job where a technician from another company could not figure out the electrical, so he just put the panel back on the electrical compartment and left the job. It is a heat pump ...

In the first installment of this series, "Calculating a practical hotspot safety margin", we discussed how two-parameter thermal models assume that the entire motor, including windings, exhibits one ...

The operation of an electric motor is typically simple and reliable, making it possible to overlook during day-to-day maintenance practices. Having a checklist makes it easy to know exactly what to ...

Build in a thermal safety margin to handle servomotors that heat up more than theoretical models predict when the torque cranks up. • The relationship between intermittent and continuous torque is ...

Brushless dc (BLDC) motors offer multiple benefits over other types of dc motors. They’re efficient, reliable, run at high speeds, are compact for their power level, and produce little or no EMI.

The internal combustion engine is found in traditional cars as the main traction element disappears and is replaced by new solutions, with electric motor and batteries at the center of the scene. This ...
