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 ...

DC motor drives are the interface between a controller and a DC motor. Their job is to convert speed and direction input from the controller to currents and voltages compatible with the motor. There ...

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 ...

The most appropriate type of low-power dc motor that can be selected for any application depends on several factors. First, determine the correct gearhead ratio when one is used; second, determine the ...

DC servomotors are DC motors that incorporate encoders and are used with controllers for providing feedback and closed-loop control. Specifically, servomotors provide precise motion and position ...

The Pittman Series 6000 brush-commutated dc servo motors are said to provide up to 40% more continuous torque—2 oz-in. for the 1.901-in.-long version—compared with other 22-mm-diameter devices.

The motor and motor control markets are thriving in a number of areas, particularly medical and robotic applications. Also, there is a rich demand for small, efficient, high- and low-torque, and high- ...

[Davide Gironi] shows us how to implement a sensorless brushless DC motor controller (sensorless BLDC) using an ATmega8 microcontroller. In order to control a BLDC motor you need to know its ...

Moticont has added a new high-force voice coil motor to its GVCM family of voice coil motors with an internal shaft and bearing. The new GVCM-095-089-03 Linear Voice Coil Motor (also known as linear ...

For decades, utility plant personnel have performed insulation resistance tests with handheld megohmmeters to prevent motor failures that lead to costly unplanned shutdowns, penalties and re-winding ...

Before embarking on your next project, it's important to brush up on the basics—the types of electric motors as well as their key components. There are two types of ac motors: synchronous and ...
