Chapter 2, Problem 2.33P
The approximate torque-speed curve and its equation for a 1/4 hp shunt-wound DC motor are shown in Figure P2-14. The rated speed for this fractional horsepower motor is 10 000 rpm at a rated voltage of 130 V. Determine:
- The rated torque in oz-in (ounce-inches, the U.S. industry standard for fractional hp motors)
- The no-load speed
- The operating speed range
- Plot the power-torque curve in the operating range and determine the maximum power that the motor can deliver in that range.
