∙ 14y agoAn AC drive, typically a Variable Frequency AC Drive, is a system for controlling the speed/torque of an AC motor by varying the frequency of the supplied power. They are commonly found in industrial HVAC applications for controlling fans.
An AC drive is defined by electricians as a variable frequency inverter and motor combination. You will find a AC drive in items that require a electrical motor. Certain clocks, remote controlled vehicles, and fans are a few of the examples.

Why commutator are not used in ac motors?
Because, the commutator segments are used for converting AC to DC.
Why capacitor is use in ac machines?
Capacitors are used in ac machines to assist the field during starting.
Why is a 3 phase induction motor is used in electric trains?
AC induction motors are not always used in trains as traction engines, however they are a popular choice. AC induction motors are very simple and reliable and aside from bearing wear they have no parts that wear out. This is because the power used by the rotating parts is supplied by the magnetism like in a transformer and so there are no slipping brushes. Most train systems actually use a DC supply, then a device called an inverter is used to convert the DC to variable frequency to drive the AC motor and control its speed. When this is done the AC induction motor is a very reliable and flexible engine and even allows energy recovery when the train is breaking.
What is the meaning of 230V ac and 50Hz ac supply?
It is an AC supply with an rms voltage of 230 v and a frequency of 50 Hz, as used throughout Europe.
Where should ac or DC supply be used?
The type of power supply being used (AC or DC) should match the power requirements of the device it will be supplying power to.
What is ac drive and how it works?
An AC Drive used for a speed control of a motor by using vary frequency.
What is the AC drive?
An AC drive is a device that converts AC power into a desired frequency to allow for AC motor speed control. This term is commonly used in engineering.
Where can someone purchase an AC drive?
One can purchase an AC drive at DriveSys, Vacon, EmersonIndustrial, Delta or GETransporation. An AC drive is a device used to control the speed of an electrical motor.
What is the meaning of a c drive?
An AC drive is a type of adjustable-speed drive used in electro-mechanical drive systems to control AC motor speed and torque by varying motor input frequency and voltage. AC drives are used in applications ranging from small appliances to the largest of mine mill drives and compressors.
What is the purpose of ac drive input ac chokes or reactors?
An AC drive is a device use for control AC motor speed, also knows as variable frequency drive, a reactor in an AC circuit is basically an inductor which will filter spikes in source voltage.and AC chokes are typically used as the inductive components in electronic filters. - roxas_riku
What is the difference between an ac drive and a dc drive?
The differenece is in the type of current it uses. AC is usually what is used in the home and DC from something like the car battery.
What kind of electricity used in train?
Ac current. Ac current is easily controlled for voltage and frequency. The diesel engine runs a generator that generates AC current for use in the electric drive motors on each drive wheel.
How does ac drive run a motor?
"A good AC drive technician understands the operation of the variable speed drive and the functions of its components.An outstanding AC drive technician also understands the effects of the load on the drive and the effects of the drive on the load."...James Shumberg
Why ac drive convert ac voltage in dc?
It is done to control the speed of the motor.
How do variable speed motors work?
A variable sped drive is sometimes also known as a variable frequency drive. These drives are used in electro-mechanical drive systems to control AC motor speed and torque.
What kilowatt of AC generator will drive a 18 kilowatt ac motor?
30kva generators ,it can be able to run the 18kw ac motor
Is it possible to run two 3Phase Motors on one AC Drive?
Yes provided the AC drive can take load of two motors. But this is not very ideal nor good
