DC drives are made up of an SCR (Silicon Controlled Rectifier) bridge that is responsible for converting incoming three or single-phase AC volts to DC volts.  This conversion process makes it possible for DC drives to regulate speed, torque, voltage and current conditions of the DC motor.  This is perfect for industrial processes like paper [...]

It will come as an interesting fact for those unfamiliar with variable frequency drives that the first electric motors available on the market were designed and built for operation from direct current power.  As such DC motors have been available for nearly 100 years.  However, AC motors have surpassed DC motors as the preferred motor [...]

AC and DC electric motors were seen as the muscle of the industrial revolution.  Ironically, these electric motors are now also regarded as the smart muscle of the computer-controlled plant and commercial facility of the future.  The advent of powerful, reliable AC drives and DC drives is keeping AC motors and DC motors in the [...]

Although new advances and technologies are nice, is it really necessary to replace all DC drives with AC drives?  Should one not rather select the most appropriate motor and drive solution for your particular application?  This is an important question being raised quite often about this topic.  Both DC drives and AC drives have their [...]

Replacement of Variable Speed Drives happens due to a number of different reasons.  Find below a list of these reasons.  Â
Existing equipment should be replaced with an AC Drives system when:

The existing DC motor nears the end of its lifespan;
Power factor and distortion are an issue, such as when the DC motor has a poor power [...]

For many years now, experts in the field of electronics have been predicting the demise of DC drives.  Due to all the benefits offered by AC drives, which include reduced maintenance and cheaper motors, they might just be right.Â
While there is no denying that AC drives are gaining more ground on the popularity front, particularly [...]

DC Motors are used for almost any kind of application you can think of. From the tiny motor that rewinds a DVD in a DVD player to the large motors used in electric automobiles, DC Motors are useful in many applications. However, without a way of controlling how fast a DC Motor operates, it is [...]

A DC Motor, or a direct current motor, converts electrical energy into mechanical energy. A DC Motor is one of the basic types of electric motors available on the market. The other type of electric motor is of course the AC Motor, or alternating current motor. Among DC Motors, there are shunt-wound, series-wound, compound-wound and [...]
