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.

這些馬達，壓力至 138 bar (2000

psi)，轉(zhuǎn)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 )，法蘭或腳架安裝,油口位置可選。

對于 M2U 和 M2-200 馬達，通常轉(zhuǎn)速能

夠到 50 至 100 r/min，取決于馬達的規(guī)

格和所驅(qū)動負載的特性。對于 25M-50M

馬達，較轉(zhuǎn)速一般是 100 r/min，允許

更一些的轉(zhuǎn)速，取決于要求的扭矩和所驅(qū)動負載的

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 馬達僅一個方向工作,在訂貨時必須

規(guī)定旋轉(zhuǎn)方向。M2-200 馬達通過使馬達油

口的流量反向,就能簡單地實現(xiàn)反向旋轉(zhuǎn)。

較轉(zhuǎn)速能夠在 50 和 100 r/min 之間變

馬達失速扭矩范圍是對于給定的跨越馬達

壓差下，在 1200 r/min 工作扭矩的 65%

和 之間，要取決于失速下軸的特殊

角度位置和供給馬達液壓流量。
