Brand: Zhuhai SV Tech Co., Ltd.

Product overview

The Zhuhai SV Tech Co., Ltd. SV Tech H3 is a high-voltage brushless motor intended for UAV and industrial equipment power systems. It accepts 200-400 V DC, has a rated input current of 2.5A and weighs 610g±10g. Integration involves its shaft extension, mounting holes, propeller mount and wiring harness, together with adequate current and cooling margins. Dimensional, installation and wiring documentation supports engineering integration. The final configuration depends on the intended operating conditions and mutually agreed specifications.

The H3 requires coordinated selection of the motor, electronic speed controller, propeller and power supply. Propeller changes affect current, thrust and temperature rise, so selection must account for the intended supply and load. Maximum thrust must not be used as sustained hovering capability. Operating ambient temperature is -10 ~ 65 °C, and bearing temperature must remain below 100 °C under worst-case conditions. Service life can reach 5000 hours, depending on load, temperature, installation and maintenance.
