Question
Chapter 41, Problem 1RQ
To determine
The two factors that determine the synchronous speed of the motor.
Expert Solution & Answer
Explanation of Solution
The speed of the consequent pole of the motor is changed by the change in the stator pole number.
The two factor that determine the speed of the AC motor is frequency of the applied voltage and the number of stator poles per phase.
Thus, the synchronous speed is changed by the frequency change and the number of stator poles.

The pinion rotates at Ta 720 r.p.m. The normal pressure angle is 20° while the helix angle is 25°. The face width is 40 mm and the normal module is 4 mm. The pinion as well as gear are made of steel having ultimate strength of 600 MPa and heat treated to a surface hardness of 300 B.H.N. The service factor and factor of safety are 1.5 and 2 respectively. Assume that the velocity factor accounts for the dynamic load and calculate the power transmitting capacity of the gears.

The gear tooth profile is involute full depth with 20° normal pressure angle. The helix angle is 23°, number of teeth on pinion is 20 and the gear ratio is 3. Both the gears are made of steel with allowable beam stress of 90 MPa and hardness 250 B.H.N.
