Rotating Motor Armature for PRO jigsaw model tmr800k (part YTMR80WR)

Replacement rotating motor armature designed specifically for the PRO tmr800k jigsaw. This rotor restores the rotating element of the jigsaw motor, enabling correct transfer of torque to the cutting mechanism and allowing the tool to regain proper rotational motion. Intended as a spare part for repair and maintenance of the specified PRO model, the armature supports reliable operation and helps extend the service life of the jigsaw when installed correctly.

Advantages

The armature is manufactured to match the mechanical and dimensional requirements of the PRO tmr800k, ensuring correct fit and alignment with the motor stator and gearbox components. The rotor's windings and commutator surfaces are prepared for consistent electrical contact and torque delivery, reducing vibration and uneven cutting motion. Using this replacement part restores original motor geometry without the need for full tool replacement, making repairs cost-effective and reducing downtime.

Suitable for

• Repairing a PRO tmr800k jigsaw with a damaged or worn rotor
• Routine maintenance when motor performance is declining
• Workshops and service centers performing power tool refurbishment
• Users aiming to restore original cutting performance of the specified jigsaw

Key specifications

• Component type: rotating armature (rotor) for a corded jigsaw motor
• Compatibility: designed for the PRO tmr800k jigsaw model
• Function: restores rotational motion and transfers torque to the cutting mechanism
• Construction: laminated rotor core with copper windings and commutator segments
• Typical installation position: inside the motor housing between bearings and commutator brushes

How to use

To replace the armature, disconnect the jigsaw from the power supply and open the motor housing according to the manufacturer’s service instructions. Remove the old rotor by detaching retaining fasteners, bearings and any associated gearbox coupling as required, then slide the replacement armature into position ensuring correct bearing seating and commutator alignment with the brush holders. Reassemble the housing and any covers, reconnect brushes or electrical connectors if disturbed, and test motor rotation without load before resuming cutting operations.

Usage recommendations

Use only with the specified PRO tmr800k model and follow safety procedures: disconnect power before servicing, inspect bearings and brushes while replacing the armature, and perform a trial run after assembly to confirm proper alignment and smooth rotation. If uncertain about fitment or disassembly, consult a qualified technician or authorized service center.
