Angle grinder No name VMS12574 (model YVMS74WS) — handheld electric grinding tool

Replacement rotor for an angle grinder compatible with No name VMS12574 (model YVMS74WS). This motor rotor is the rotating core component of the grinder's electric motor, intended to restore rotational movement and torque in a handheld electric grinding tool. It is designed for repair and maintenance of the specified angle grinder to recover motor function and mechanical performance.

Advantages

The rotor is manufactured to match the mechanical and dimensional requirements of the original motor, providing consistent rotation and balanced operation when correctly installed. Using a dedicated replacement rotor helps avoid intermittent operation, reduces vibration caused by worn running surfaces, and supports stable torque delivery under load. As a direct-fit component for the specified model, it simplifies repair work and reduces the need for full motor replacement.

Suitable for

• Repairing No name VMS12574 handheld angle grinder (model YVMS74WS)
• Replacing a worn or damaged motor rotor in the specified grinder
• Maintenance tasks to restore smooth rotation and torque
• Workshops and service technicians performing small electric motor repairs

Key specifications

• Type: electric motor rotor for handheld angle grinder
• Function: rotating core delivering torque to the grinder spindle
• Compatibility: designed for the No name VMS12574 angle grinder model
• Typical materials: laminated steel core with conductive windings and shaft
• Intended use: replacement part for repair and maintenance

How to use

Before installation, disconnect the grinder from power and allow any moving parts to stop. Disassemble the grinder housing and motor following the manufacturer's service instructions to access the rotor assembly. Remove the old rotor carefully, inspect bearings, commutator or slip rings, and the stator for wear or damage. Install the replacement rotor ensuring correct axial alignment and secure fit on the motor shaft, then reassemble the motor and housing. Test the tool at low speed to confirm smooth operation and absence of excessive noise or vibration before returning to normal use.

Usage recommendations

Check bearings, brushes (if applicable), and commutator condition when replacing the rotor to ensure full restoration of motor performance. Use appropriate safety equipment and follow electrical safety procedures during repair. If unsure about disassembly or rotor fit, seek assistance from a qualified service technician.
