How does a frequency drive work?
Frequency drives are an adjustable-speed drive used for electro-mechanical drive systems. They control the motor speed and torque by varying motor input frequency and voltage.
How speed of a squirrel cage induction motor can be varied?
There are two ways of changing the speed of AC motors,by altering the frequency or the number of poles in the motor. An increase in frequency of the supply voltage to the motor will cause it's speed to increase while reducing the frequency will causes the motor speed to drop. This is the method exploited by Variable Speed/Frequency Drive. The second method of changing the number of motor's stator poles is the difficult. The manufacture must design the motor such that the number of the motor's pole in operation can be increased or reduced. Increasing the number of poles increases the stator flux density which decreases the speed. Decreasing the number of poles does the opposite. This method is typically found in two speed motors and it's rarely used compared to VSDs.
What is the speed of DC series motor at no load?
No load speed is the speed that the motor run when it has no load, i.e., the motor is separated from the engine, that speed is than greater than the rated speed, because the rated speed is the speed whwn the motor are linked to the load and it is the full load.
Why is a synchronous speed motor considered a constant speed motor?
synchronous motor is a constant speed motor because it will only run at a synchronous speed or not at all.the speed can be changed by changiing the frequency only ns=120f/p
Which DC motor is constant speed motor?
Dc shunt motor is constant speed motor.Its speed is constant with armature current.This shunt motor is used in paper mills and drilling machines
Will two speed power glide tran work with a 350 Chevy motor?
yes
How do you wire a two speed pool motor?
Your pool control system must be capable of handling a two speed motor. You'll have to go to the manual to determine connections for your specific motor and controller. You can't effectively use a two speed motor if your control system is not designed and programmed for such a motor.
How many contactors are required for two speed motor?
two
What would cause your blower motor to work on only one speed on a 97 Chevy k1500?
If the one speed it works on is high speed, it is the blower motor speed resisitor that is bad.
What would cause the blower motor on a 2002 Malibu to work only at high speed?
I would suspect the blower motor speed resister is shot.
Your heater blower will just work on high speed?
The blower motor speed resistor is burned out. The high speed function bypasses the resistor. The speed resistor is generally located near to the blower motor.
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.
What happens to speed when toque increases in bldc motor?
When torque increases in a BLDC motor, the speed decreases. This is because as more torque is applied, the motor has to work harder to maintain the same speed. The relationship between torque and speed is inversely proportional in BLDC motors.
Your ac want blow how do you fix it?
If you are saying the blower motor will not work, then check the fuse. If the fuse is not blown, then it is possibly a defective Blower Motor Resistor Pack, blower motor, or blower motor speed control switch, in that order.If you are saying the blower motor will not work, then check the fuse. If the fuse is not blown, then it is possibly a defective Blower Motor Resistor Pack, blower motor, or blower motor speed control switch, in that order.
How is a car motor work?
Gas and a spark are the two necessary things that make a car motor work.
What type of transmission fluid does 5 speed manual B16A motor takes?
Honda Manual Transmission Fluid is recommended for a 5-speed manual B16A motor. Amsoil Manual Transmission Fluid will also work in a 5-speed manual B16A motor.
How does a furnace multi speed motor work?
Mutli speed furnace motors work on a basis of horse power verses work load. The motor actually contains multiple windings or you could say multiple motors. Each of the windings has a specific horse power rating at a given work load. For example, a 3 speed 1/2 horse power motor is actually 3 different horse powers. High is 1/2 hp - medium is 1/3 hp - low is 1/4 hp. As the motor horse power is decreased the motor will slow down under a given or constant work load. Technically there is no such thing as a multi speed motor but in actuality a multi horse power motor.
