The electric drill suddenly did not turn, took apart and installed to move, and did not move again
If the above two items are all out of order, the stator winding and rotor winding of the brush shall be checked for burnout (visual inspection and instrument inspection). No matter the stator winding or rotor winding is broken, it can cause the whole circuit to be disconnected the electric drill does not turn.The above view is for your reference.
Check brush. See if the brush is too short to wear so that the spring of the press brush does not press to the brush - causing the brush to be out of contact with the commutator so that the drill does not turn. It is also necessary to see whether the springs of the press brush lose their elasticity at high temperatures - which also causes the brush to be out of contact with the commutator and prevents the electric drill from turning.
Turn on the drill clips by hand when the power is not turned on and try to see if the whole drive system is jammed. If it is possible that the gears and bearings are damaged, they need to be repaired and replaced.
