Descripción detallada

This equipment is equipped with a robust motor that features a durable structure and high wear resistance, ensuring a long service life even in harsh working environments such as high load, high temperature and frequent start-stop, which reduces maintenance frequency and overall operational costs. The motor is approved for very high rotational speeds, enabling stable and reliable operation at extreme high-speed conditions without excessive vibration, noise or component damage, making it suitable for high-speed hydraulic drive scenarios requiring efficient power output. It has a high control range and can be swiveled to zero displacement, allowing flexible adjustment of output flow from maximum to zero, realizing precise control of the hydraulic system and avoiding energy waste. It offers a variety of control options to adapt to different system requirements, and can be optionally equipped with mounted flushing and boost-pressure valve to enhance oil cleanliness and maintain stable boost pressure. Additionally, it can be optionally configured with an integrated or mounted counterbalance valve to prevent load drift and ensure safe operation. Adopting a bent-axis design, it optimizes power transmission efficiency, reduces internal mechanical wear, and ensures compact structure while enhancing operational stability.

Selección y solicitud de cotización

The A6VM series is used in mobile drive circuits where torque, speed and installation envelope must match the machine layout. Confirm displacement, speed range, case drain routing and mounting interface before ordering.

Rango de velocidad

The minimum rotational speed nmin is not restricted. Please consult us regarding applications requiring uniformity of the rotatory motion at low speeds.

1)The minimum and maximum displacement can be steplessly adjusted,(standard setting for sizes 250 to 1000 if ordering code is missing.Vgmin =0.2×Vgmáx, VG máximo = Vgmadrex)

2) The values are applicable:

-for the optimum viscosity range from Velegir=36 to 16 mm2/s

-with hydraulic fluid based on mineral oils

3)Observe limitation of displacement due to counterbalance valve

4) Torque without radial force, with radial force.

Aviso

▶Valores teóricos, sin eficiencia ni tolerancias; valores redondeados

▶Operation above the maximum values or below the minimum Values may result in a loss of function, a reducd service life or in the destruction of the axial piston unit. Other permissible limit values, such as speed variation, reduced angular acceleration as a function of the frequency and the permissible angular acceleration at start (lower than the maximum angular acceleration) can be found in data sheet 90261.
