What else can I help you with?
Single phase motor speed is determined by the?
frequency of the power supply it is connected to. The speed of a single phase motor is directly related to the frequency of the alternating current (AC) power supply. As the frequency of the power supply changes, the speed of the motor will also change.
Replace two speed electric motor with single speed electric motor?
Replace with single speed of the same electrical, speed, and mechanical considerations for mounting, choosing the preferred speed from the existing two speed. In general it is common practice especially in the HVAC industry to replace a three speed motor with a four speed motor, using only three of the speeds that match the existing. Replacement must be with a single speed of the same horsepower, torque, and other electrical considerations of the needed or preferred two speed choice of speeds. Often the choice of speed, changes the horsepower or torque.
Why do you control the speed of DC motors?
because dc motor is a powerful & dangerous motor it is akiller
What is the purpose of a motor controller?
A motor controller is a device that controls an electric motor. Most motor controllers require a manual and automatic function, forward and reverse rotation, and speed control.
How does the generator terminal voltage rise and the motor speed fall when the brushes are given a backward shift in a generator or forward shift in a motor?
A generator is a back up of power. A generator can only give so much voltage.
What other wiper motors can fit a 1965 Chevy Impala?
Need to know if you have a single speed or two speed wiper motor.
The synchronous speed of a four pole 60 hz single phase motor is?
3600 rpm
How the motor starts?
An inductionor asynchronous motor is a type of AC motor where power is supplied to the rotor by means of electromagnetic induction, rather than a commutator or slip rings as in other types of motor. These motors are widely used in industrial drives, particularly polyphaseinduction motors, because they are rugged and have no brushes. Single-phase versions are used in small appliances. Their speed is determined by the frequency of the supply current, so they are most widely used in constant-speed applications, although variable speed versions, using variable frequency drives are becoming more common. The most common type is the squirrel cage motor, and this term is sometimes used for induction motors generally.
How many Methods can be use to control the speed of Single Phase Induction Motor?
How many methods can be used to control the speed of Single Phase Induction Motor? 1.injecting emf method 2.by frequency control method 3.induced voltage method
Performance curve of a single phase induction motor?
The performance curve can be a graph of torque versus speed. The torque is zero at zero speed and also at the synchronous speed. Normally an induction motor operates at 90-97% of the synchronous speed, where the slip is between 10% and 3%. In this region the torque is proportional to the slip. As the torque is increased the speed falls until the motor stalls and the speed drops to zero. Below the stalling speed the torque rises between zero speed and the stalling speed. Because the torque is 0 at 0, a single-phase induction motor needs a separate starting winding fed by a starting capacitor to produce a little positive torque that starts the motor.
How do you change fan speed on central heating unit?
The motor is either single or two speed. You can change the size of the pulleys if yours has a belt. If it is direct drive, it runs at the speed it does.
Why use clutch plate in single phase motor?
induction motors have very little starting torque as the motor come up to speed it reduces the torque load until it gets near synchronous speed
