Hydraulic Motors – Frequently Asked Questions
Where are hydraulic motors used?
Hydraulic motors are used in a wide range of applications. They are found wherever rotary drive is needed. Application areas include agricultural machinery, plastic injection molding machines, sweepers, wheel drives for construction equipment, conveyor drives, tunnel boring machines, winches, and many more.
What types of hydraulic motors are there?
The short answer: quite a few, just like with cars.
Instead of diesel, petrol, electric, and hybrid, there are (external) gear motors, gerotor motors (also known as oil motors or orbital motors), and vane motors. Then there are axial piston motors in bent-axis and swash plate designs, rotators, and radial piston motors.
Which hydraulic motor is suitable for which application?
It's like choosing a grill: Do I want a charcoal grill for the smoky aroma? Or a gas grill for convenience? The right decision depends entirely on the application. There are some overlaps, making it hard to clearly differentiate.
Gear motors are often used for fan drives in hydraulic oil coolers. Orbital motors are widely used in construction, agricultural, and municipal machinery. Vane motors are common in injection molding machines and winch drives. Axial piston motors are frequently found in hydrostatic drives, often combined with planetary gearboxes. Radial piston motors are used in wheel drives and also in plastic injection molding applications.
What torque can a hydraulic motor deliver?
The torque a motor can produce depends on its displacement and the pressure or pressure differential (i.e. inlet pressure minus outlet or return pressure). Low-speed hydraulic motors are designed to generate high torque even at low speeds.
What output power can a hydraulic motor deliver?
The output power of a rotary motor depends on the flow rate provided by the hydraulic pump and the pressure differential. Power is directly proportional to speed, which makes high-speed motors well-suited for high-power applications.
What do you want to power with the hydraulic motor?
Before selecting the right hydraulic motor, you should answer the following questions:
- What torque is required for the application?
- What speed should the hydraulic motor achieve?
- Are there minimum or maximum speed requirements?
- What oil flow rate does your existing hydraulic system provide?
- What hydraulic pressure can your pump generate?
- What drive power is available?
If you’ve answered all these questions, you're well on your way to selecting the right motor.
Can the speed of a hydraulic motor be adjusted?
There are fixed displacement and variable displacement motors. Some motors (e.g. axial piston or radial piston motors) are adjustable and allow direct control of speed. With other types, additional hydraulic valves are required (e.g. flow control valves).
Are hydraulic motors from different manufacturers interchangeable?
The answer is: it depends. A chocolate bar might look the same on the outside, but you only see the content when you unwrap it. A 1:1 replacement isn’t always straightforward.
- Gerotor / oil motors are generally easiest to replace. Many series are identical in mounting flange, oil ports, and output shafts.
- With gear motors, replacement is also relatively simple between brands. However, the devil is in the details: while they may look similar externally, there can be major differences in performance, pressure capacity, and efficiency.
- Vane motors are less common today, but several manufacturers still exist. It's difficult to say who is interchangeable with whom – vane motors are not exactly our strongest area, but we try to present their pros and cons.
- With axial piston motors, there are market leaders that are not easily interchangeable. Danfoss, Bosch Rexroth, and Linde are the Mercedes, BMW, and Audi of axial piston motors – but in many cases, a VW is good enough. And that's where we come in.
- Radial piston motors are also not easy to replace without expertise. Looking for a replacement for a Poclain motor? Or an alternative to an SAI radial piston motor? Often, there is a solution – and asking doesn't cost a thing.
How can I recognize good-quality hydraulic motors?
For us, performance data such as volumetric efficiency, continuous peak power, and overall quality are not a foreign concept. We've been in the hydraulics industry for 18 years and know what customers need. Poor quality, performance loss, bad service – that’s no longer acceptable today. Not for manufacturers, nor for dealers.
As a distributor, we have access to multiple sources. This allows us to offer our customers the best price-performance ratio. Of course, our hydraulic motors must meet strict quality criteria defined and verified by us. This ensures consistently high quality.
