Introduction to the New Technology of HA6VM Series Hydraulic Motors (Displacement 55-215

The HA6VM series hydraulic motors adopt a swash shaft axial piston design and are suitable for both open and closed circuit hydrostatic transmission. They cover displacements ranging from 55 to 215 (models such as HA6VM55MA and A6VM107EPL), with nominal pressures of 400/450 bar and peak pressures reaching 450/500 bar. It meets the requirements of high rotational speed (up to 6150 rpm) and large torque (for example, the A6VM215 model has a torque of up to 1550 Nm at nominal pressure). Its core advantages include:

1. Stepless variable regulation: The displacement can change steplessly from Vg max to 0. The output speed is proportional to the flow rate. The torque increases with the increase of pressure difference and displacement, suitable for complex working conditions.

2. High efficiency and energy saving: The design of high power density and low moment of inertia ensures excellent starting characteristics and low energy loss, meeting the demands of energy-saving construction machinery.

3. Long service life and reliability: With a reinforced bearing system and precise manufacturing processes, it supports long-term operation in

harsh environments and is widely used in excavators, cranes, concrete pumps and other equipment.
