http://www.szpowerdrive.com/news/can-a-vfd-drive-a-slip-ring-motor.htm WebThe brake test in a direct method of testing. It consists of applying a brake to a water – cooled pulley mounted on the shaft of the motor. A rope is wound round the pulley and its two ends are attached to two spring balances S1 and S2. The tension of the rope can be adjusted with the help of swivels. Then,
WebAt values of slip lower than ˆs, the curve falls steeply down to zero at s = 0. The torque at synchronous speed is therefore zero. At values of slip higher than s = ˆs, the curve falls slowly to a minimum value at s = 1. The torque at s … WebWe would like to show you a description here but the site won’t allow us.
WebSep 10, 2024 · Speed Control of Slip Ring Induction Motor 1) By Varying External Resistance: We know that a motor uses an external high resistance circuit for producing high starting torque. The resistance of this motor depends upon … WebWhile running on load, the brake drum is cooled by pouring cold water. PROCEDURE: 1. Connect the circuit as per the circuit diagram. 2. Switch on the supply at no load. Take one set of reading at no load. 3. Vary the load in suitable step and hence note down all the meter reading up to 100 % of full load.
WebFeb 24, 2012 · A Squirrel cage induction motor does not contain Brushes, Slip rings and Commutators. Due to this reason, the cost of the motor is quite low. However, Slip Rings are used in Wound type induction motor to add external resistance to the rotor winding. Due to the absence of Brushes, there are no sparks in the motor.
