 Sizing Your Motor

To properly size a Automotive Lift Repair Florida hydraulic motor or pump for your machine or application, you need to estimate the required speed, torque, and horsepower. This process often demands more expertise compared to selecting an electric motor. If you require assistance, GS Global Resources is available to help.

 In Summary

Effective Automotive Lift Repair Florida hydraulic motor selection begins with understanding the performance requirements of the application and then working backward to select the appropriate pump. Evaluate the cost of motor options in relation to the complexity of your system. Use the basic formulas provided on the following page to guide your selection process.

 Hydraulic Motors Overview

They work in conjunction with a hydraulic pump, which transforms mechanical power into hydraulic power. Hydraulic motors provide the force and motion necessary to drive external loads.

Types of Hydraulic Motors

There are three primary types of hydraulic motors commonly used today: gear, vane, and piston motors, each with various styles available. Additionally, there are less common types like gerotor or gerolor (orbital or roller star) motors.

Hydraulic motors can be classified as either fixed- or variable-displacement and operate in either bi-directional or uni-directional modes. Fixed-displacement motors maintain a constant speed as long as a constant input flow is provided, while variable-displacement motors allow for varying flow rates by adjusting the displacement. 

Torque Types

Torque, which is the rotational force produced by the Automotive Lift Repair Florida motor, is measured in inch-pounds (in.-lb), foot-pounds (ft-lb), or Newton-meters (Nm). There are three types of torque to consider:

– Breakaway Torque: The minimum torque needed to start the motor without any load, overcoming internal friction.

– Running Torque: The torque required to keep the motor or load in motion.

– Starting Torque: The minimum torque needed to start the motor under load, combining the force needed to overcome the load and internal friction.

The mechanical efficiency of a hydraulic motor can be determined by the ratio of actual torque to theoretical torque.

Displacement and Flow Rate

The displacement of a hydraulic motor is defined by the oil volume introduced into the motor during one revolution of the output shaft, measured in cubic inches per revolution (in³/rev) or cubic centimeters per revolution (cc/rev). This can be calculated by summing the volumes of the motor chambers or by manually measuring the oil collected during one revolution.

Flow rate refers to the volume of oil introduced into the motor per unit time, measured in gallons per minute (gpm) or liters per minute (lpm). It can be determined by multiplying the motor displacement by the running speed or by using a flowmeter. Manual measurement can also be done by collecting fluid during one revolution.

Motor Designs

– Gear Motors: These are generally the most cost-effective and suitable for medium pressures and flows. They have two gears, with high-pressure oil flowing between them to generate motion. Gear motors are durable and less likely to fail quickly, but leakage between the inlet and outlet can affect efficiency and create heat.

– Vane Motors: Vane motors have a housing with an eccentric bore and vanes that slide in and out, driven by pressurized fluid. They offer medium pressure ratings and high flows, with a mid-range cost.

– Automotive Lift Repair Florida Piston Motors: Available in radial, axial, and other less common designs. Radial-piston motors have pistons arranged perpendicularly to the crankshaft’s axis, while axial-piston motors have pistons arranged in a circular pattern. Axial-piston motors come in swashplate and bent axis designs, differing in the alignment of the pistons and drive shaft.

– Gerotor and Roller Star Motors: These less common designs offer benefits such as lower friction, higher efficiency, and smoother operation. Roller star motors have longer lifespans with less wear compared to gerotor designs.

Selecting Hydraulic Motors

When choosing a hydraulic motor, consider the following factors:

– Maximum operating pressure, speed, and torque requirements.

– Displacement and flow needs within the system.

– Compatibility with different fluid types, such as bio-based, environmentally-friendly, or fire-resistant fluids.

– Resistance to contamination.

– Cost, including initial price and expected lifespan, as well as efficiency ratings and ease of maintenance.

– Size and weight, which affect the overall system or machine.

Choosing the right hydraulic motor involves balancing performance, cost, and maintenance considerations to ensure optimal system efficiency and longevity.
