How to ring out the stator of an angle grinder
Posted: Mon Feb 17, 2025 5:32 am
When checking the rotor windings of an electric drive, the following should be carried out:
complex manipulations. A winding break can be in any connection with a single plate of the collector. Therefore, it is necessary to check the resistance between all the plates of the collector , alternately applying indicator probes to them. If there is no break, the resistance in all cases will have the same small value. Any deviation means a break. A winding breakdown on the body is checked with probes when they contact the collector and the "iron" from a set of sheets of electrical steel. The indicator scale should not respond to this action.
However, it is impossible to determine the interturn circuit using a multimeter. A device called a short-circuited loop indicator (SCLI) is used here. More details on this in the information below.
The stator as an element of the electric drive of the angle grinder is involved in the creation of an electromagnetic field in which the rotor rotates, creating torque on the spindle shaft. During operation, it fails thailand telegram data for a number of reasons . The user can diagnose damage and repair the stator independently.

On the interturn circuit, indicator
The operating principle of the interturn fault detection device is shown below. The device induces a magnetic field in the winding under test . If the winding has shorted turns, the short-circuit current causes increased resistance to the electromagnetic field created by the device. By adjusting the ISC, a setting is made, upon reaching which a light signal is triggered (the indicator color changes from green to red) or a soundtrack is played.
