WIRNIK SILNIKA for jigsaw VZR570 / TMR570 (model YVZR57WS)

Spare motor rotor WIRNIK SILNIKA for jigsaw VZR570 / TMR570 (model YVZR57WS) is a replacement armature designed to restore the electrical-to-mechanical conversion in compatible handheld jigsaws. The rotor is the rotating element of the motor that works with the stator to drive the saw’s blade mechanism. This part is intended for use during motor repair or component replacement when the original armature is worn, damaged, or produces reduced cutting performance.

Advantages

The rotor is manufactured to match the form and function required by VZR570 and TMR570 jigsaw designs, providing correct shaft dimensions, winding configuration, and balance to ensure stable operation. Replacing a faulty armature can recover motor torque and speed characteristics, reduce vibration, and extend the working life of the tool without the need to replace the entire motor assembly.

Suitable for

• Repair of VZR570 handheld jigsaw
• Repair of TMR570 handheld jigsaw
• Restoring blade drive performance after motor failure
• Workshops performing electrical motor component replacement

Key specifications

• Component type: rotating armature (motor rotor)
• Compatibility: models VZR570, TMR570
• Function: converts electrical input into mechanical rotation for blade drive
• Typical materials: laminated iron core with copper windings and rotor shaft
• Fit: designed for direct replacement in specified jigsaw models

How to use

To replace the rotor, disconnect the jigsaw from power and remove the housing and protective covers according to the tool manufacturer’s disassembly procedure. Carefully extract the old armature from the motor assembly, noting the position of bearings, brushes and any retaining clips or spacers. Fit the replacement rotor in the correct orientation, reassemble the motor with proper seating of bearings and brushes, and restore the housing and fasteners. After reassembly, test the jigsaw under no-load conditions to verify smooth rotation and correct electrical connections before normal use.

Usage recommendations

Use original or equivalent quality replacement parts and follow standard safety precautions: disconnect power before service, avoid contact with exposed windings, and ensure bearings and brushes are inspected or replaced as needed to prevent premature wear. If unsure about the repair procedure, consult a qualified technician.
