Motors may be used as retarders but

not as hydraulic brakes. When a motor

is used as a retarder, adequate

pressure must be provided at the inlet

port to prevent cavitation. Systems

requiring positive holding capabilities

(braking) must be provided with

externally operated mechanical holding

devices.

The maximum pressure obtainable in

a system using a motor as a retarder

(pumping) is dependent upon speed.

At speeds below 1000 r/min, maximum

obtainable pressure is proportionally

diminished relative to speed as speed

approaches stall.

这些马达，压力至 138 bar (2000

psi)，转速至 2800 r/min，扭矩有 2.0，2.8

或 4.0 Nm/6.9 bar (18,25 或 35 lb.in./100

psi )，法兰或脚架安装,油口位置可选。

对于 M2U 和 M2-200 马达，通常转速能

够到 50 至 100 r/min，取决于马达的规

格和所驱动负载的特性。对于 25M-50M

马达，较转速一般是 100 r/min，允许

更一些的转速，取决于要求的扭矩和所驱动负载的

Consult your Vickers representative

before using motors as retarders, or if

braking is required.特性。

M2-200 Standard Models

Back pressure must not exceed: 75% of

supply pressure at 1800 r/min; 80% at

1200; 85% at 600. (Supply and back

pressures are actual operating

pressures at the ports of the motor.) In

circuits where back pressure exists, a

relief valve is required in both the inlet

and outlet ports.

M2U 马达仅一个方向工作,在订货时必须

规定旋转方向。M2-200 马达通过使马达油

口的流量反向,就能简单地实现反向旋转。

较转速能够在 50 和 100 r/min 之间变

化，取决于马达的规格和驱动负载的特性。

较转速能够在 50 和 100 r/min 之间变

化，取决于马达的规格和驱动负载的特性。

马达失速扭矩范围是对于给定的跨越马达

压差下，在 1200 r/min 工作扭矩的 65%

和 之间，要取决于失速下轴的特殊

角度位置和供给马达液压流量。
