HP 30 Technical Information

Product catalog summary

General Information
HP 30 motors offer design flexibility with various configurations such as displacement, output shaft, port configuration, and mounting flange. Key benefits include low pressure drop, high starting torque, and capability for two-speed and series circuit operations. The standard motor supports close shaft loads, while the wheel motor integrates within wheel hubs to optimize bearing life. The balance plate reduces leakage and protects against temperature differences, and the extreme duty seal guard offers enhanced protection in harsh conditions.

Single Speed Motors
Technical specifications for single-speed motors include geometric displacements ranging from 344 cm³/r to 677 cm³/r, with corresponding maximum speeds and torques. These motors are designed for continuous and intermittent operations with specific pressure and flow ratings. Proper initial operation involves running the motor at reduced pressure and flow to ensure longevity.

Performance Data
Performance data is provided for various displacements, highlighting efficiency across torque and speed ranges. Motors should operate within specified conditions for optimal life.

Installation and Maintenance
Installation instructions cover bearingless mounts and shaft installation, emphasizing the importance of maintaining appropriate case pressure and porting advantages. The document also outlines model codes for easy identification.

Two-Speed and Brake Motors
Two-speed motors offer additional flexibility with detailed specifications and hydraulic circuit diagrams. Brake motors are available in single and two-speed configurations, with specific dimensions and load capacities.

Applications
HP30 motors are suitable for a wide range of applications including harvesters, augers, forestry equipment, grinders, mixers, drilling, material handling, metal forming, sprayers, and skid steer loaders.

Specifications and Performance Data
The document provides performance data for various motor displacements, including 434 cm³/r, 480 cm³/r, and 677 cm³/r. It emphasizes that WHITE reserves the right to alter products without notice and disclaims responsibility for errors in printed materials.

Dimensions and Mounting
Details are provided for standard, wheel, and bearingless mounts, including main port specifications and standard rotation directions. Motor dimensions are listed for different displacements, with specific measurements for A Max and B dimensions.

Installation Instructions
Instructions for bearingless mount installation include specifications for internal spline material and dimensions, oil circulation requirements, and seal provisions. Spline and shaft specifications are detailed, including pressure angles, number of teeth, and fit types.

Shaft and Load Capacity
The document outlines shaft side load capacity, noting that case pressure affects allowable thrust loads. It provides multiplication factors for radial load calculations at various speeds and emphasizes the importance of maintaining recommended case pressures to ensure motor longevity.

Case Pressure and Porting
HP30 series motors require careful management of case pressure, especially in closed loop applications where a case drain line is necessary. Benefits of case porting include contamination control, cooler motor operation, and extended seal life.

Model Code and Configuration
A 30-digit model code system is used to specify motor configurations, ensuring all desired features are included when ordering.

Two-Speed Motor Description
The HP30 series includes a two-speed feature allowing shifts between low speed high torque (LSHT) and high speed low torque (HSLT) modes. The motor is bidirectional and supports shift on the fly technology, requiring an external control valve for mode changes.

Overview: The document provides technical specifications and operational details for the HP30 two-speed hydraulic motor, manufactured by WHITE Drive Motors & Steering LLC. It outlines the motor's functionality, performance data, specifications, and operational guidelines.

Specifications: The HP30 motor operates in two modes: Low Speed High Torque (LSHT) and High Speed Low Torque (HSLT). The motor's geometric displacement varies between 229 cm³ to 677 cm³ depending on the mode. Maximum speed and torque values are provided for both continuous and intermittent operations.

Operational Modes: The motor shifts between LSHT and HSLT modes using an integral selector valve. The transition is controlled by pilot signal pressure, which must exceed 10.3 bar over case pressure to switch to HSLT mode. The motor requires a minimum pilot pressure of 3.5 bar and can handle up to the full operating pressure.

Performance Data: In LSHT mode, the motor's torque and speed are equivalent to a conventional HP30 motor. In HSLT mode, speed increases by 50% while torque decreases by one-third. The motor can operate in both clockwise and counter-clockwise directions.

Technical Information: The document includes detailed tables with maximum speed, torque, oil flow, and pressure ratings. It emphasizes the importance of maintaining a minimum delta pressure of 50 PSID between motor ports and outlines the maximum allowable pressures for inlet, return, and case.

Operational Guidelines: Recommendations include using premium quality hydraulic oil, maintaining system temperatures below 82°C, and ensuring proper filtration per ISO Cleanliness code 4406: 20/18/13. The document warns against thermal shock and provides guidelines for motor break-in procedures.

Dimensions and Mounting: Dimensions for standard, wheel, and bearingless mounts are provided, along with port specifications. The document includes schematic diagrams for closed and open loop circuits, highlighting the necessity of a case drain in certain configurations.

Additional Notes: The document includes disclaimers about potential errors and the right to alter product specifications without notice. It also mentions conversion kits for adapting motors between open and closed loop configurations.

Overview: The document provides detailed technical specifications and features of a multi-disc brake system designed by WHITE Drive Motors & Steering LLC. The brake system is integrated with a motor to form a compact package, offering various features and specifications suitable for low-speed, high-torque applications.

Key Features:

Automatic application of the brake via a spring when hydrostatic pressure is absent, ensuring safety.
Environmentally protected design with no need for adjustments.
Boost feature to enhance holding capacity, matching the motor's full output torque.
Multiple plumbing options facilitated by two sets of release and boost ports.
Available with or without an outer grease seal.

Applications: The brake system is suitable for skid steer loaders, trenchers, road rollers, and other machinery requiring load-holding capabilities in low-speed, high-torque drive systems.

Specifications:

Static Holding Torque: Minimum 780 N-m without boost, up to 3570 N-m with maximum boost.
Release Pressure: Minimum 10.3 bar for full release, with a maximum of 68.9 bar allowed at the release port.
Case Pressure: Continuous 1.4 bar, with a maximum of 3.5 bar.
Boost Pressure: Continuous 15.2 bar, with a maximum of 34.5 bar.
Speed: Maximum operational speed of 360 rpm.
Emergency Braking: Capable of meeting parking requirements after three consecutive stops.

Dimensions:

Single-speed and two-speed brake motor dimensions are provided, with detailed measurements for various displacements.
Standard rotation and port pressurization details are included for both single-speed and two-speed configurations.

Brake Shaft Side Load Capacity: The document includes curves indicating radial load capacity on the motor shaft, with adjustments based on case pressure and bearing life expectations.

Additional Information: The document contains disclaimers regarding potential errors and the right to alter product specifications without notice. It also includes contact information for WHITE Drive Motors & Steering LLC and its subsidiary in Poland.

The HP30 uses a balance plate to reduce the leakage over the face of the rotating Geroler. This device also protects the motor from high temperature differences between the fluid from the pump and the fluid communicated to the motor. Extreme duty seals are engineered to equipment working in harsh conditions, such as cement augers, dredgers, fertilizer and salt spreaders, tillers and other machines that require power wash-downs. The two piece seal features two channels, one stationary and one that rotates with the motor shaft. In between the channels is a greased cavity used to reduce friction...
