Description
Stator Current Collector Spring Rings d15 mm / thickness Ø3 mm (set of 2 pcs.)
The set of current collector spring rings (stator contact springs) with an inner diameter of ~15 mm and a winding thickness of 3 mm is designed to ensure constant and reliable electrical contact in the commutation unit of the stator and brush holders of corded power tools. The spring spiral design fits the contact unit tightly, effectively compensating for vibrations, sparking, and thermal expansion under high loads.
Key Advantages and Features:
- Stable Current Transmission: Constant spring pressure eliminates contact loss and prevents burning of current-carrying lamellas and wires.
- Flexible Wire Lead: Each ring is equipped with a twisted copper lead for convenient soldered or terminal connection to the stator winding.
- Heat Resistance: Made of high-quality copper-plated spring alloy with excellent electrical conductivity, resistant to wear and high temperatures.
Compatibility and Application:
Used in rotary and stationary stator commutation units of power tools from various global and Chinese brands (Makita, Bosch, DeWalt, Interskol, Dnipro-M, DWT, Sturm, etc.):
- Rotary hammers and demolition hammers.
- Angle grinders (grinders / AG).
- Corded drills, screwdrivers, routers, and mixers.
