产品概述

The dual-motor product consists of two motors arranged back-to-back, designed to achieve higher operating speeds than traditional swashplate designs. Furthermore, the compact structural design integrates a high displacement, enabling a wider speed conversion range without the need for modular transmissions. The HMV-02D is 30% lighter and has a smaller footprint compared to motor-transmission assemblies. Additionally, maximum motor efficiency is achieved by evacuating hydraulic oil from the housing. The dry housing reduces churning losses, thereby decreasing the input power required to drive the motor.

产品优势

High starting torque and high speed.

High efficiency.

No transmission required.
