Product overview
The SVTECH SV-UT4214 from Zhuhai SV Tech Co., Ltd. is a compact three-phase brushless motor for UAV propulsion. Its 185 g mass, 15-26 V DC input range and 22.2 V (6S) rated voltage define the basic electrical and weight requirements for integration. It supports clockwise and counterclockwise rotation when viewed from the shaft end. Installation planning must account for motor outline, mounting holes, screw length, available mounting space, complete-aircraft mass and the required thrust.
The motor has separate KV340 and KV440 electrical specifications, so supply, ESC and propeller selection must follow the chosen winding and its current limits. Final delivery configuration and propeller requirements depend on operating conditions and agreed documents. Maximum current is 25 A for KV340 and 32 A for KV440; the higher 28.2 A and 50 A test points do not extend those limits or establish continuous-duty ratings. Operation is specified at -10 ~ 65 °C, while storage requires -10 ~ 50 °C and relative humidity no greater than 85%.
