2. A 50-kW, 440-V, 50-Hz, six-pole induction motor has a slip of 6 percent when operating at full-load conditions. At full-load conditions, the friction and windage losses are 300 W, and the core losses are 600 W. Find the following values for full-load conditions: (a) The shaft speed nm (940 r/min) (b) The output power in watts (50 kW) (c) The load torque Tad in newton-meters (508 Nm) (d) The induced torque Tuna in newton-meters (517 Nm) (e) The rotor frequency in hertz. (3.00 Hz)

A DC series motor will _______if operated without a load. a. Operate a rated speed b. Operate slower than rated speed c. Operate slightly higher than rated speed d. Run away

Short answer please please please please...
