SP-24/30/36/38 STATOR & ELECTRIC ASSEMBLY INGCO (CIWLI2085)-N-33
The INGCO N-33 Stator & Electric Assembly (SP-24/30/36/38) is a complete OEM replacement motor stator and electronics module for the INGCO CIWLI2085 20V Brushless Cordless Lithium-Ion Impact Wrench (850 Nm fastening / 1000 Nm nut-busting). This integrated assembly includes the stator coil, electronic control board (ECU), hall sensors, wiring harness, and thermal overload protection, forming the stationary core that generates the electromagnetic field to drive the brushless rotor. Designed for high-efficiency power delivery, it restores full variable speed (0–2400 RPM), impact rate (0–3200 IPM), and torque control when the original fails due to heat, dust, or electrical surge. As a critical spare in INGCO's professional-grade lineup, it enables field-level repairs without replacing the entire motor housing.
Key Features:
- Brushless Stator Core: High-purity copper windings on laminated silicon steel for minimal energy loss and heat buildup; supports 20V lithium-ion input with >90% efficiency.
- Integrated Electronics: Onboard MOSFET controller with hall-effect sensors for precise rotor positioning, 3-speed electronic selector, and reverse auto-stop function.
- Thermal & Overload Protection: Built-in PTC thermistor and fuse prevent burnout during prolonged high-torque use (e.g., lug nut removal).
- Compatibility: Direct plug-and-play fit for CIWLI2085 (all variants); color-coded connectors ensure foolproof installation—no soldering required.
- Durability: Epoxy-potted electronics resist vibration, moisture, and dust (IP54-equivalent); rated for 500+ hours under full load.
Ideal For:
- Mechanics, fleet maintenance crews, or construction teams servicing the CIWLI2085 after heavy use (e.g., tire shops, scaffolding assembly).
- Replace when symptoms include no power, intermittent operation, burnt smell, or error LED flashing.
- Not compatible with brushed models or other INGCO impact wrenches (e.g., CIWLI2001).
Installation:
- Remove battery and housing screws (T20 Torx).
- Disconnect old stator harness (3 plugs).
- Unbolt stator (4 screws), lift out.
- Install new assembly, reconnect, reassemble.
- Test all speeds and LED indicators.
Time: 20–30 minutes | Tools: Torx set, pliers
