A DC motor can be constructed in various ways, and each design has specific performance characteristics, particularly regarding speed and torque production. The rotor is basically the same in all DC ...

To some, motor speed control is somewhat of a mystical science, a science that causes motors and machines to sometimes operate in unexpected ways. Over 30 years ago, AC drives were considered "new ...

With their optimised magnetic circuit and special rotor, the new brushless DC motors from Maxon deliver an impressive amount of torque. The EC-i 52 drives are considered to be high quality at an ...

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 ...

Industrial applications use direct current motors because the speed-torque relationship can be varied to almost any useful form -- for both motor and regeneration applications in either direction of ...

Selecting a motor for a specific application can be a challenging task. Many factors must be considered, including the application’s required voltage, maximum current and diameter, speed, efficiency, ...

BOHEMIA, N.Y., 4 Aug. 2014. Data Device Corp. (DDC) in Bohemia, N.Y., is introducing the PW-82560N0 speed and torque brushless DC electric motor controller for military applications such as gun ...

This application note discusses the advantages and benefits in using a BLDC motor to drive a DC brushed motor. For a BLDC controller that uses hall effect devices, there are six steps in the ...

In electrical terminology, a parallel circuit is often referred to as a shunt. Hence, DC motors in which the armature and field windings are connected in parallel are referred to as DC shunt motors.

To some, motor speed control is somewhat of a mystical science, a science that causes motors and machines to sometimes operate in unexpected ways. Over 30 years ago, AC drives were considered "new ...
