Structure of rotary piston compressor_Characteristics of rotary piston compressor <img src="{{media url="Structure_of_rotary_piston_compressor_Characteristics_of_rotary_piston_compressor.jpg"}}" alt="" />Structure of rotary piston compressor Rotary piston compressor, also known as rolling rotor compressor, is mainly composed of 3 parts: casing, motor assembly and compressor assembly. Since there is no reciprocating part, the space volume can be reduced, making the whole structure compact and light.

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.
