Firma 2100Kv Brushless Sensored Crawler Motor
Brand: Spektrum
Part No: SPMXSM3001
Supplier Stock: Expected May 23rd
Request Stock NotificationThe Spektrum Firma 2100Kv Brushless Sensored Crawler Motor (SPMXSM3001) delivers smooth, low‑cog control and dependable torque for 1/10 scale crawlers, rock racers and trail rigs on 2S–3S LiPo. Its 4‑pole, 8‑magnet rotor, CNC‑machined aluminium housing, precision bearings and insulated high‑purity copper windings are engineered for durability and consistent, low‑speed throttle response. Pre‑installed 3.5mm gold‑plated bullets make installation straightforward, and the water‑resistant sensor lead features a locking plug and gasket for added reliability.
Key Features
- Excellent upgrade for 540 brushed motors with the same diameter and mounting pattern (vehicle must accept pinions with a 1/8" bore)
- Balanced speed and torque for trail and scale crawling applications
- High‑quality 4‑pole sintered rotor for strong, smooth power
- Polarity protection via magnetic encoder for precise phase signalling — match wire colour to ESC connectors
- 3.5mm gold‑plated bullet connectors pre‑installed
- Waterproof sensor wire with locking plug and gasket
- Precision ball bearings and hardened steel 1/8" shaft
- Sensored FOC control for excellent low‑speed modulation
