Name two requirements that must be met before a motor can be used for wye-delta starting.

Expert Solution & Answer
Check Mark
To determine

Identify two requirements for a motor to be used with wye-delta starting.

Explanation of Solution

Wye-delta starting is used to reduce the inrush current and the starting torque. The two requirements for a motor to be used with wye-delta starting are:

  • The design of the motor must be such that the stator winding is connected in delta during the running time.
  • All the leads of the stator windings must be accessible.

The equation of the turning moment diagram for the three crank engine and the equation of the moment required by a machine connected to this engine are given below: Engine Torque Machine Torque T=10000-500 sin (40) T=10000+2000 sin (20) N.m N.m where radians is the crank angle from inner dead center and the mean engine speed is 300 rpm. It is required to select a proper flywheel (find the moment of inertia of the flywheel in kgm2) and then calculate the power of the engine if the total percentage fluctuation of speed of the flywheel is ±1% of the mean speed. Calculate the angular acceleration of the flywheel when angle is 45°.
