1.Positioning or residual torque: when there is no current passing through the winding, the torque required to make the output shaft of the motor rotate. 2.Driver: an electrical control device used to run the stepping motor. This includes power supply, logic programmer, switching element and a variable frequency pulse source which determines the step rate. 3.Dynamic torque: the torque produced by the motor at a certain step rate. The dynamic torque can be expressed by PULL IN torque or PULL OUT torque.

How to deal with the faulty host refrigerant system of the compressor
How to deal with the faulty host refrigerant system of the compressor How to deal with a main engine refrigerant system where the compressor has burnt out or failed is a more serious and technically demanding problem than the production of a new main engine. However, it is often neglected by most of the technicians, and even the wrong concept is replaced if they think that it is broken anyway! It causes some disputes that the compressor quality is poor or others use it improperly.
