Type PM stepping motor low price is one great advantage, the air gap between the stator and rotor is about 0. 25毫米。 Bearing using sliding bearing (套金属)And the structure of the type PM stepping motor as shown in figure 2 sections. When you have special demand, can use cantilever structure form of figure 4. Figure 4 for its appearance. The thickness of the motor is 14 mm, outside diameter of 68 mm, is flat, there are 100 pole rotor, step from the Angle of 1. 8 degrees. The structure of the rotor shaft thrust bearing, to ensure that the air gap between the stator inner diameter and outer diameter of the rotor is fixed. Sliding bearing series of metal and resin series, metal series, iron series oil bearing or copper oil bearing. Iron series oil bearing is suitable for low speed and high load, copper base oil bearing is suitable for high speed light load, speed reducer bearing use metal series in the majority. Oil-retaining bearing with porous sintered metal material, can be stored in the hole, using effect of pump shaft rotation. Form the oil film between the bearing and shaft, resin is a oilless bearing, bearing with its low cost, suitable for light load condition. the main products: stepper motor, brushless motor, servo motor, stepping motor drive, brake motor, linear motor and other kinds of models of the stepper motor, welcome to inquire.
