Description
Overview:
This 110 V field coil (stator) is a genuine Makita replacement designed for selected compact angle grinders. Built with copper windings and a laminated steel core, it forms the stationary part of the motor and is essential for reliable power transfer and consistent performance. It is engineered to fit Makita GA4030R and GA4530R models, with the same specification also used on the GA5030R. Supplied as an original Makita part, it matches factory electrical characteristics for safe, efficient use on 110 V site supplies common in the UK. Use it to restore lost power, erratic speed, or overheating caused by a failed or damaged field. OEM number 633901-3 ensures correct identification and a straightforward like-for-like replacement.
Key Features:
- Genuine Makita part for assured fit and compatibility (OEM 633901-3)
- 110 V specification for use with UK site transformers and tool circuits
- Precision-wound copper windings to meet factory electrical performance
- Direct-fit for GA4030R, GA4530R, GA5030R with no modifications required
- Restores torque, speed stability, and overall motor efficiency
- Durable insulation and core materials for long service life
