Without getting into a long-winded dissertation about torque, we're going to suggest that you dig through your old copies of HOT ROD Magazine and familiarize yourself with the relationship between ...

Classic radial gap, stacked lamination stators. (Shown with and without windings.) As we look at catalogs of electric motors, we find them classified by power, speed, and torque. To a large extent, ...

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 ...

Most known for their versatility, electric motors have revolutionised the way we view the core definition of power, qualifying it as effective energy expenditure concerning work done over time. Among ...

Stepper motors resemble servo motors in that both types are characterized by an ability to rotate a partial turn and then stop for any interval with or without holding torque. In addition, both motor ...

A brushless-DC motor is common in ceiling fan and pan-tilt-zoom (PTZ) camera designs. But you can’t use the same brushless-DC motor solution for both of these end products. A ceiling fan driver ...

Oversizing often happens when engineers try to match the inertia between the load and the motor rotor, so that they can tune the drive’s velocity, torque or position loop relatively tightly to meet ...
