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 ...

Full-voltage, single-speed motor starters: Single-speed squirrel-cage motors have starters that fall into two categories: full-voltage or across-the-line starters; and reduced-voltage starters.

A fundamental understanding of the speed-torque curve it the key to specifying a dc motor that will do everything it needs to do. Much has been written about the process of selecting motors for ...

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.

One of the more popular three-phase electrical services supplied to medium-size commercial buildings is the Wye or Star configuration transformer. The name comes from the transformer’s secondary ...

Bipolar stepper motors are used in many applications, from driving paper through a printer to moving an XY stage in industrial equipment. Typically, the motors are driven and controlled by inexpensive ...

To achieve EV potential by squeezing more functionality into a given volume, and delivering value at a compelling price point, means there are strong incentives for integrating motor and inverter.
