General maintenance, don't need so much: a set of wrenches, screwdrivers, pullers and hammers. These are basically enough. Bearing heaters are sometimes used. These are used for daily motor maintenance: bearing oiling and replacement.

If you check the motor, you will use a multimeter and a shaking table (DC resistance measurement, phase-to-phase insulation, ground insulation, etc.). ).

If you want to overhaul, you will use the following things:

Winding machine, winding die, special-shaped flat shovel (multiple pieces), forming rod, electric soldering iron, multimeter, shaking table, etc.

Materials: enameled wire, insulating paint, white wire, fine cotton rope, highland barley paper, wire pressing, yellow wax pipe, etc.
