Answer the following statement(s) true (T) or false (F)
1. Standard motor efficiency is calculated by the simple formula of watts output of the motor divided by watts input. 2. To reduce losses due to eddy currents in the motor, high-grade steel with a higher silicon content is used to reduce the friction of the magnetic materials and therefore reduce the heat produced in changing the magnetic fields of the motor iron. 3. I2R losses can be reduced by decreasing the wire size in the stator winding. 4. A high-efficiency motor is designed to run at 94.1% efficiency at full load. 5. Power factor typically improves with the hp rating of the motor and tends to peak about 75% to 100% of full load.
