Product overview

The T-MOTOR U15Ⅱ KV80 is a DC brushless motor designed for high-power industrial multirotor UAVs, including emergency rescue, freight transport and passenger-carrying propulsion. It supports 12-24S lithium batteries and uses a 36N42P slot and pole configuration with a 20mm shaft. The KV80 version has 17mΩ resistance, a no-load current of 3.8A and maximum continuous power of 1932W. The U15Ⅱ family also offers a KV100 winding option with 12mΩ resistance, 4.5A no-load current and 2150W maximum continuous power.

Custom imported high-temperature-resistant copper windings and specially selected imported bearings form the motor’s construction. Bearing selection accounts for simulated axial and radial operating loads, with bearing service life exceeding 1000 hours in normal use; fault-free motor operation under load reaches 1000 hours. The motor measures Φ 147.5×55 mm and weighs 1740g including its 100mm enameled-wire leads. For the KV80 configuration, the recommended propeller is the T-MOTOR G40*13.1-inch one-piece carbon-fiber propeller.
