Illustrated in this project is the use of stepper motors in order to generate electricity that may be used to power LEDs, charge some batteries or even drive a motor. Illustrated in this project is ...

Design engineers know that both brush DC and brushless DC (BLDC) motors can operate as generators, but many tend to avoid running brushed DC motors in generating mode because they believe it is ...

Sizing conductors and protection for rotating electrical equipment is commonly required in the field and on exams. The rules ...

Stepper motors are synchronous motors that step at the pulse rate of the driving signal. For the motor to move quickly, the stepping rate must be fast. However, because of motor and load inertia, the ...

ROSSLYN, Va. — The National Electrical Manufacturers Association (NEMA) announced it has revised NEMA MG 1-2016 Motors and Generators. NEMA MG 1 assists users in the proper selection and application ...

Today, most electric machines operate with radial flux (RF). Magnax offers a new concept, though—a machine that operates with axial flux (AF). Figure 1 provides a comparison of the RF and AF ...

The quest for energy efficient electric motors has generated a lot of interesting ideas. One of the latest is said to push the efficiency of induction motors to better than super-premium levels by ...
