In the catalogs the following rated parameters of asynchronous motors are provided in most cases: the power [P.sub.n], the rotation speed of the rotor [n.sub.n], the phase current of the stator [I.sub.1n], the efficiency factor [[eta].sub.n], the power factor cos [[phi].sub.n], the relative breakdown torque [[mu].sub.c], the relative starting torque [[mu].sub.p], etc.
The i-th relative breakdown torque and the starting torque are calculated:
Locked-rotor current, locked-rotor torque, and breakdown torque
tests were conducted at 60 hertz and near rated voltage.
NORD says based on decades of industry experience, it implements application-specific motor winding patterns to ensure tough torque characteristics with high breakdown torques
. The durable roller table motors handle demanding load situations such as high-frequency reversing operation.
