Specifications

TPL = Total power losses (Watts)

TRMS = RMS torque for the application (lb-in)

Vmax = Maximum motor speed in application (RPM)

Pld = Logic Power Losses Drive (Watts)

Psr = Shunt Regulation Losses (Watts)-(RSR-2 losses or equivalent)

Note

TRMS * Vmax / 1500 = Power Stage Dissipation = Pp

A more accurate calculation would include even more specifics such as actual torque delivered at each speed plus actual shunt regulator usage. For help in calculating these please contact our Application Engineering department with your system profiles and loads.

Speed Torque Curves

Continuous ratings of the MG and NT motors are based on 100°C (212° F) motor case temperature and 25°C (77° F) ambient temperature with the motor mounted to an aluminum mounting plate as shown in the table below.

Motor

Mounting Plate Size

MG-205 and 208, NT-207 and 212

6” x 6” x .25”

 

 

MG-316 through 490

10” x 10” x .375

 

 

MG-4120

12” x 16” x .5”

 

 

Speed torque curves are based on 240 VAC drive operation.

All specifications are ±5 percent due to motor parameter variations.
