1 piece, 1 marking board, 1 crimping board, 1 elbow scissors, 1 needle nose pliers, 1 hacksaw.

2. One 1.1KW three-phase squirrel cage motor.

3. 1 DC separately (parallel) excited motor (100W)

4. 1 steel disassembly and assembly table, specifications: 1500mm×750mm×780mm

5. 1 set of soldering iron and soldering iron stand

Disassembly methods and steps of three-phase asynchronous motor

(a) Cut off the power supply, disassemble the connecting wire between the motor and the power supply, and mark the power supply wire correspondingly to avoid mistaking the phase sequence during recovery, and insulate the ends of the power supply wire.
(b) Prepare all disassembly tools, especially special tools such as pullers and sleeves.
(c) Be familiar with the structural characteristics and disassembly and assembly methods of the disassembled motor.
(d) Measure and record the distance between the coupling or pulley and the pillow block.
(e) Mark the phase sequence of the power cord in the junction box, the outlet direction of the motor and the outlet direction of the lead wire on the machine base.
2. Disassembly steps
As shown in Figure 1, briefly describe the disassembly steps:
(a) Remove the pulley or coupling, and remove the fan cover at the rear of the motor.
(b) Remove the positioning keys or screws and remove the fan.
(c) Unscrew the front and rear end cover fastening screws, and remove the front bearing outer cover.
