Firma 3150Kv Brushless Motor

The Spektrum Firma 3150Kv Brushless Motor (SPMXSM1000) is a 3660-size, sensorless unit designed as a strong choice for 1/10 scale 4WD models. It offers smooth, efficient power delivery with a low-cog 4‑pole, 8‑magnet rotor and precision bearings, and arrives preinstalled with 4mm gold-plated bullet connectors for straightforward installation. It also serves as a practical upgrade path from many 540- and 550‑size brushed motors that share the same diameter and mounting pattern, provided the vehicle accepts pinions with a 5mm bore.

Features

• Perfect upgrade for many 540/550 brushed setups of the same diameter/mounting pattern (vehicle must accept 5mm-bore pinions)
• Low-cog 4‑pole, 8‑magnet rotor with high-quality sintered construction
• CNC machined aluminium housing for strength and heat dissipation
• Insulated high-purity copper windings for efficiency
• Hardened alloy steel 5mm output shaft
• High-precision ball bearings for smooth rotation
• Preinstalled 4mm gold-plated bullet connectors
• Well matched with the Spektrum Firma 130 Smart ESC
