Product overview
The STEAM Steam 4035HS12S540KV MK6079 brushless motor is designed for 600-class helicopters and manufactured using CNC combined turning and milling. Internal active cooling fins support heat dissipation and energy conversion efficiency. Its stator measures 40mm in diameter and 35mm in thickness, with a 12N stator-arm and 10P magnetic-pole configuration. The motor has a 49.6mm outside diameter, a 60mm body length and a weight of 415g. Mounting dimensions are 25mm/30mm.
Rated at 540kv, the motor supports a maximum 12s battery configuration. Maximum continuous current is 85A and maximum continuous power is 3500w; peak limits are 95A and 4300W for 2 seconds. No-load current is 4.3 a at 10v, and motor resistance is 18mΩ. The 6mm-diameter shaft has a total length of 98mm and a gear shaft length of 38mm. Supplied equipment comprises one motor, four M4×8MM socket head cap screws, three Φ5.5 gold-plated banana connectors and three heat-shrink tubes.
