Rotor (wirnik) for hammer drill motor TMM1350 model YTMM0586, spare part for TMM1350 (86)

Replacement rotor (wirnik) for the TMM1350 hammer drill motor, model YTMM0586, is an armature component designed to convert electrical input into rotational motion within the motor assembly. It is intended as a spare part for maintenance and repair of TMM1350 units and for restoring motor performance when the original rotor is worn, damaged, or defective. The part is compatible with hammer drill motors that match the specified model and mechanical dimensions.

Advantages

This rotor provides the essential rotating element of the motor, helping to re-establish consistent torque and rotational speed. It is manufactured to match the original form and function for straightforward replacement, enabling technicians to restore motor operation without requiring a full motor replacement. Using a correct-fit rotor reduces downtime and can be a cost-effective solution for repair and maintenance of TMM1350 hammer drills.

Suitable for

• Repair and maintenance of TMM1350 hammer drill motors
• Replacement of worn or damaged armature in compatible hammer drills
• Workshop and field repairs where restoring motor rotation is required

Key specifications

• Component type: Motor rotor (armature)
• Intended application: Hammer drill motor
• Compatibility: Designed for motors matching TMM1350 mechanical and mounting specifications
• Function: Converts electrical energy into rotational motion; transmits torque to the drive system
• Installation: Fitment into existing motor stator with appropriate bearings and brushes

How to use

Before installation, disconnect power and remove the motor from the tool according to the manufacturer’s service instructions. Disassemble the motor housing and remove the old rotor, noting the condition and orientation of bearings, washers, and brushes. Install the replacement rotor ensuring correct seating in the bearings and alignment with the commutator and brush assembly. Reassemble the motor, verify brush contact and free rotation by hand, then test the motor under no-load conditions before returning the tool to service.

Usage recommendations

Use only compatible bearings, brushes, and insulating parts when fitting the rotor. Inspect bearings and commutator for wear and replace those components if necessary to ensure reliable operation. Verify proper brush spring tension and clearance to prevent arcing and premature wear. After installation, perform a brief no-load run to confirm smooth rotation and verify that there are no abnormal noises or vibrations.
