Product overview
The DYS BE1104 brushless motor has five configurations: 4000, 5400, 6500, 7500 and 10000 KV. Each has an 11mm stator diameter, a 5mm stator length and a 1.5mm shaft diameter. Overall motor dimensions are Φ14×12.5mm, expressed as diameter × length, and weight is 5.6g. These physical specifications remain the same across the configurations. The choice of KV therefore changes the electrical ratings and pull value while retaining the same stated motor dimensions, stator dimensions, shaft diameter and weight.
The 4000 KV configuration uses a 3-4s LiPo battery range and has maximum continuous ratings of 5.5A and 81.4W, with 190g pull. The other four configurations use 2-3s LiPo batteries. At 5400 KV, maximum continuous current is 6.5A, power is 72.2W and pull is 184g; at 6500 KV, these values are 10.9A, 121W and 215g. The 7500 KV configuration has corresponding values of 11.8A, 161W and 230g, while the 10000 KV configuration has 20A, 222W and 280g. Each configuration thus carries its own battery range and continuous electrical limits.
