1 The Series motor is the leader in its class, offering high efficiency with rugged durability. The three-zone orbiting disk valve, laminated manifold and Roller Stator motor work harmoniously to produce high overall efficiencies over a wide range of operating conditions. The standard case drain increases shaft seal life by reducing internal pressures experienced by the seal. The case leakage is also directed across all driveline components, increasing motor life. An internal drain option is also available. At the heart of the motor is a heavy-duty drivelink, offering 30% more torque capacity than competitive designs. These features make the Series motor the motor of choice for applications requiring peak efficiency for continuous operation. Features Heavy-Duty Drive Link is up to 30% stronger than competitive designs for longer life. Three-Zone Orbiting Valve precisely meters oil to produce exceptional volumetric efficiency. Standard Case Drain increases shaft seal life by reducing pressure on seal. Rubber Energized Steel Face Seal does not extrude or melt under high pressure or high temperature. Forced Drive Link Lubrication reduces wear and promotes longer life from motor Displacement in 3 /rev (cm 3 /rev) 3.2 (52) 4.6 (76) 5.4 (89) 6.8 (111) 7.7 (127) 10.0 (164) 12.5 (205) 15.5 (254) 17.9 (293) 24.9 (409) Max Speed RPM Cont.

18 Operating Recommendations CAUTION! - White Hydraulics motors/brakes are intended to operate as static or parking brakes. System circuitry must be designed to bring the load to a stop before applying the brake. CAUTION! - Because it is possible for some large displacement motors to overpower the brake, it is critical that the maximum system pressure be limited for these applications. Failure to do so could cause serious injury or death. When choosing a motor/ brake for an application, consult the performance chart for the series and displacement chosen for the application to verify that the maximum operating pressure of the system will not allow the motor to produce more torque than the maximum rating of the brake. Also, it is vital that the system relief be set low enough to ensure that the motor is not able to overpower the brake. To ensure proper operation of the brake, case drain back pressure must be maintained at 500 psi or less. Case drain back pressure above 500 psi can result in erratic operation of the brake. To avoid potential problems with the operation of the brake, a separate case drain line is recommended. Use of the internal drain option is not recommended due to the possibility of return line pressure spikes. A simple schematic of a system utilizing a motor/brake is shown in Figure A below. Although maximum brake release pressure may be used for an application, a 500 psi pressure reducing valve is recommended to promote maximum life for the brake release piston seals. To achieve proper brake release operation, it is necessary to bleed the release line and brake release cavity once all connections are made. To facilitate this operation, all motor/brake feature two release ports. One or both of these ports may be used to release the brake in the unit. Motor/brakes should be configured so that the release ports are near the top of the unit in the installed position. Once all system connections are made, one release port must be opened to atmosphere and the brake release line carefully charged with fluid until all air is removed from the line and motor/brake release cavity. When this has been accomplished the port plug or secondary release line must be reinstalled. In the event of a pump or battery failure, an external pressure source may be connected to the brake release bleed port to release the brake, allowing the machine to be moved.
