Electric Motor Remanufacturing and the Circular Economy
When an electric motor fails or its efficiency drops, the first question that usually comes to mind is "should I buy a new one?" Yet a motor's life does not end with its first faul... More Details
How Low-Loss Electrical Steel Laminations Improve Motor Efficiency
How Low-Loss Electrical Steel Laminations Improve Motor Efficiency When we list the factors that determine an electric motor's efficiency, the first things that usually come to min... More Details
Electric Motor Selection for Industrial Heat Pumps
For many years, industry produced heat by burning fuel. Today this equation is changing: industrial heat pumps take low-temperature waste heat and lift it to the higher temperature... More Details
Diagnosing Broken Rotor Bars with Motor Current Signature Analysis (MCSA)
Diagnosing Broken Rotor Bars with Motor Current Signature Analysis (MCSA) One of the most critical yet hardest-to-reach parts of an asynchronous motor is its rotor. The rotor forms... More Details
Choosing Pump and Fan Motors for Data Center Cooling
At the heart of a data center sit the servers, but the infrastructure that keeps those servers running without interruption is the cooling system. If the heat produced by thousands... More Details

dv/dt and Reflected-Wave Overvoltage on Long Motor Cables The cable between a frequency inverter (VFD) and an asynchronous motor is a component that is often overlooked, yet it is ... More Details
Shaft Voltage and Bearing Currents in VFD-Driven Motors
Shaft Voltage and Bearing Currents in VFD-Driven Motors Driving an asynchronous motor with a frequency inverter (VFD) brings major advantages in energy savings and flexible speed c... More Details
The Oversized-Motor Trap: Why Efficiency Drops at Partial Load
When buying an electric motor, many businesses reach for a slightly larger frame "just to be safe." On the surface this feels prudent, but it quietly turns into a trap that drains ... More Details
Electric Motor Mounting Types: B3, B5, B14 and B35 Compared
The correct operation of an electric motor depends not only on its power, speed and efficiency, but also on how it is mounted. The way the motor connects to the machine, that is th... More Details
Electric Motor kW, HP and RPM Equivalents
When you look at the nameplate of an electric motor, you see that the power is sometimes written in kilowatts (kW) and sometimes in horsepower (HP). The speed is given as revolutio... More Details
How to Read the IE Efficiency Class From a Motor Nameplate
The small metal plate on an electric motor is, in effect, that motor's identity card. Among the codes printed on this nameplate, perhaps the most asked about and the most critical ... More Details
