Full load torque of induction motor?
The full load torque of an induction motor is the maximum torque it can produce at its rated speed when operating at full load conditions. This torque is necessary to drive the load at the desired speed under normal operating conditions. It is an important parameter to consider when selecting a motor for a specific application.
How many frequent start and stop operation possible for induction motor?
There is no fixed limit on the number of start and stop operations for an induction motor. However, frequent start and stop operations can lead to increased wear and tear on the motor, affecting its lifespan. It is advisable to minimize frequent start and stop operations to prolong the motor's longevity.
What is the solution for running three phase induction motor at voltage less than its rated voltage to drive full load?
The solution to this problem is to get the same size motor in HP at the correct voltage. This way the motor can correctly drive the connected full load without tripping the motor protection.
What is a CSIR motor?
A CSIR motor stands for Capacitor Start-Induction Run motor, which is a type of single-phase induction motor commonly used in household appliances like refrigerators and air conditioners. It uses a capacitor to provide the starting torque needed to initiate rotation, then operates as a standard induction motor once up to speed.
What are the advantages of open end winding induction motor over conventional induction motor?
Open ended induction motor - i assume you are talking about split phase induction motor. With these motors old style speed controlling method using external resistors can be used. However this is now obsolete.
Can 3 phase induction motor start and run rated speed by 2 phase?
yes, It would run as long as the motor was not coupled to a load. Coupled to a load the motor would have no torque and would stall.
Why each phase no load power factor of 3 phase induction motor is not same?
That indicates a fault in the induction motor.
Load test on 3 phase induction motor?
When you do a load test on a 3-phase induction motor you are checking the power factor, viz slip, and efficiency of the motor. You can test various loads with this test.
Why is the PF of an induction motor low for light loads?
Induction motor by design is inductive load. Hence the PF tends to be lower
Why is my single phase induction motor drawing to many amps?
I have a single phase induction motor. It draws 8 amps on start up and climbs to 14-15 amps when I put a load on it. When I don't have a load it runs at 1 and climbs to 2-3 amps. It is normal operation for this motor to run at the lower number of amps with a load. But I don't know what is wrong.
How do you start single phase induction motor?
capacitive start motors start by themselves however a normal single phase induction motor requires a starter motor to 'kick-start' the motor into action.
Difference between transformer and induction motor?
1. Induction Motor has an air-gap but transformer has no air gap rather it is mutually link. 2. Induction Motor has high no-load current than transformer. 3. Induction Motor is a dynamic device. 4. Induction Motor has high power factor.
What is the load current of 90kw induction motor?
90/3=30ma
Why wattmeter shows negative reading during no load condition of 3phase ac induction motor?
no load means the motor is acting like a coil
Applications of induction motor?
A single phase induction motor is mainly used in fans.It is capacitor start capacitor run induction motor.In three phase induction motor squirrel cage induction motor is mainly used in elevators,lifts,cranes.slip ring induction motor is mainly used in electrically driven ships.
When is efficiency of 3phased Induction motor maximum what is the condtion for maximum efficiency in induction motor?
It is maximum at about 75% to 100% of the motor rated load. Efficiency is maximum at unity power factor , when R=X and when variable losses Is equal to constant losses at rated load.
Why speed of the induction motor falls when load is increased?
As the load increases, the speed reduces to deliver the increased torque required.
