9%, the full-load rated speed of the motor is 1765 RPM. 2 Lb-Ft. NEMA design B motors are general purpose single speed motors suited for applications that require normal starting and running torque such as conveyors, fans, centrifugal pumps, and machine tools. 9% 25 0 D 0 10 20 30 40 50 60 70 80 90 100 % Synchronous Speed 49 Starting current is also referred to as locked rotor current, and is measured from the supply line at rated voltage and frequency with the rotor at rest. Full-load current is the current measured from the supply line at rated voltage, frequency and load with the rotor up to speed.
Using the sample 30 HP, 1765 RPM motor discussed previously, torque can be calculated by transposing the formula for horsepower. 2 Lb-Ft 1765 A graph, like the one shown below, shows the relationship between speed and torque the motor produces from the moment of start until the motor reaches full-load torque at rated speed. This graph represents a NEMA B motor. 300 275 250 225 200 175 150 125 100 75 50 25 0 0 10 20 30 40 50 60 70 80 90 100 % Synchronous Speed 46 Starting torque Starting torque (point A on the graph) is also referred to as locked rotor torque.

A conveyor, for example, may require 200% rated torque for starting. If a motor is capable of 200% torque at 200% current, and the drive is capable of 200% current, then 200% motor torque is possible. Typically drives are capable of producing 150% of drive nameplate rated current for one (1) minute. If the load requires more starting torque than a drive can deliver, a drive with a higher current rating would be required.
