yes
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.
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.
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.
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.
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.
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.
That indicates a fault in the 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.
Induction motor by design is inductive load. Hence the PF tends to be lower
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.
capacitive start motors start by themselves however a normal single phase induction motor requires a starter motor to 'kick-start' the motor into action.
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.
90/3=30ma
no load means the motor is acting like a coil
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.
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.
As the load increases, the speed reduces to deliver the increased torque required.
