Motor Selection. NEMA Class. The National Electric Manufacturers Association (NEMA) classifies motors as NEMA A, B, C, and D, depending on the relationship between torque and speed. Design B motors are by far the most common and are used for most fan, pump and compressor applications. Source: Nadel et al., 1991. Motor Speed

Oct 28, 2014 · This spreadsheet is automated to calculate efficiencies for 100 torques between 0 N·m and the stall torque you enter. It automatically updates the two graphs to specify how four design parameters for your motor are dependent on the torque delivered by the motor. The first graph shows efficiency (in blue) and motor output power (in red).
