1.Rotor pressing:
Press the rotor core and shaft together to form the rotor basic structure.Use a pressure gauge to detect the bonding force between the shaft and the rotor to ensure that it is firm and not loose.Use a yaw meter to detect the runout of the shaft to ensure that the axis is stable and the rotation is smooth.Use a hardness tester to detect the hardness of the shaft to ensure that it meets the design requirements and improves wear resistance and service life.
2.Rotor finishing:
Fine grinding the outer circle of the rotor to improve surface finish and accuracy.Cleaning the rotor to remove oil and impurities generated during processing.Deburring the rotor tooth grooves to prevent noise and wear during operation.
1.Stator grinding:
Hone the inner hole of the stator to improve surface finish and dimensional accuracy.
2.Stator ultrasonic cleaning:
Cleaning the stator to remove oil and impurities generated during the winding process.
3.Stator inner insp:
Use the core rod to detect the size and shape of the stator inner hole to ensure that it meets the design requirements.
4.Assemble skeleton insulation
Install skeleton insulation inside the stator to prevent coil short circuit and leakage.
5.Stator winding:
Wind the coil in the stator slot to form an electromagnetic field.During the winding process, the number of coil turns, wire diameter and arrangement must be strictly controlled to ensure electromagnetic performance.
6.Welding circuit board:
Weld the control circuit board to the stator or motor housing for external control.
7. Welding motor lead wire:
Weld the motor lead wire to the coil to ensure reliable electrical connection.
8.Stator comprehensive test:
Conduct electrical performance tests on the stator, including resistance, insulation resistance, inductance, etc., to ensure that the performance meets the standards.
1.Prepare components:
Prepare the rotor assembly and stator assembly to ensure that all parts are clean and free of impurities.As semble the rear end cover: Install the rear end cover on the stator assembly and fix it.
2.Install wave pads:
Install wave pads in appropriate positions to adjust the gap and shock absorption.
3.Clean the rotor:
Clean the rotor again to ensure that there is no oil and impurities.Apply anti-rust oil: Apply anti-rust oil on the rotor to prevent rust.
4.Install the front cover and screw it:
Install the front cover and tighten the screws to ensure sealing and fixation.
5.Magnetization:
Magnetize the motor to form the required magnetic field.
6. Mount the lead wire cover block:
Install the wire block to fix the motor lead wire to prevent loosening.
Whole machine inspection：
Inspect the assembled stepper motor, including electrical performance, mechanical performance, noise, vibration, etc., to ensure that all indicators meet the design requirements.
Nameplate and packaging：
Affix a nameplate to the motor housing, marking the model, specifications, production date and other information.Pack the motor to prevent damage during transportation.
