A DC drive is a kind of equipment ordinarily do control a speed, tension and current on a Direct Current Motor (DC Motor), in order to have a certain process transformation under control.

Why choke used in dc drives?
choke is used before drives to reduce the source supply fluctuation problem , which will effect drives
What are HT and LT drives?
HT drives are the pumps or motors operate at more power typically more than 0.5 Amps at 110 or 220 V DC whereas LT drives operate at lesser power less than 0.5 Amps at 24 V DC or 240 V AC.
Can you run fan on dc?
If you mean by that a normal home ceiling fan, No, you can't. Because it is an AC motor inside that. If you use fans using DC motors ,motors like the ones used in many toys for example or the ones used inside the earlier cassette or vcr tape drives, yes ,you can use DC.
Why do you give DC excitation to AC Synchronous motor?
If the synchronous motor is running near synchronous speed, it will begin rotating at synchronous speed when DC is applied to the rotor. Source: Electrical Machines, Drives, and Power Systems Theodore Wildi Section 17.3
Is it possible to run a DC brushless motor without an electronic driver?
No. In a "regular" DC motor, the permanent magnets form the stator, and the brushes and commutator are used to get the DC to the rotor windings. In a brushless DC motor, the magnet is the rotor, and the stator is a group of coils arranged in a circle to form the stator. The electronic controller drives the individual coils in the stator. There isn't a good way to drive them without an electronic controller. A link is provided to the Wikipedia article on the brushless DC motor (BLDC). At least surf on over and check out the pics. The ones showing motors that have been taken apart are particularly helpful.
Are ac drives better than dc drives?
Yes, ac drives are better than dc drives. You can find more info at en.wikipedia.org/wiki/Variable-frequency_drive or www.avtron.com/ac_vs_dc.htm
What is the working principle of AC and DC drives?
Personally, AC and DC drives are quite easy to understand. DC drive is a device that uses AC as a power source to control the DC device.
What are dc drives main functions?
DC drives are direct current motors. They are lower in cost and easier to control as compared to AC drives, which are also known as alternating current motors.
Why choke used in dc drives?
choke is used before drives to reduce the source supply fluctuation problem , which will effect drives
What are three types of power converters used in adjustable speed DC drives?
Three types of power converters viz., uncontrolled, half controlled and full controlled are used in adjustable DC drives.
What is amplidyne?
An amplidyne is a form of electromechanical amplifier in which an AC motor drives a DC generator.

What has the author A Emrah Orhun written?
A. Emrah Orhun has written: 'Forced-commutated convertor-controlled DC drives'
What is the difference between Variable Speed Drive and Variable Frequency Drive?
A variable frequency drive (VFD) refers to AC drives only and a variable speed drive (VSD) refers to either AC Drives or DC Drives. VFD's vary the speed of an AC motor by varying the frequency to the motor. VSD's referring to DC motors vary the speed by varying the voltage to the motor.
What is a SCSI hard drive used for?
SCSI is most commonly used for hard disks and tape drives, but it can also be used to connect a wide range of other devices, including scanners and DC drives.
