Radial Piston Motors - Efficiency and performance for hydraulic systems
A radial piston motor is a powerful hydraulic drive solution in which several pistons are arranged radially around a drive shaft in a star configuration – ideal for applications with high torque and comparatively low speeds. At LöSi, you will find a selection of high-quality radial piston motors that are characterised by their compact design, robust construction and high efficiency. This design is particularly suitable for industrial or mobile hydraulic systems where precision, durability and power are required.

What is a Radial Piston Motor?
A radial piston motor is a top-class fixed displacement hydraulic motor, often referred to as a "star motor". Unlike axial piston motors, the pistons here are arranged in a star shape (radially) around the drive shaft.
This special design with internal support makes it the ideal low-speed motor (HTLS). This means: It converts hydraulic pressure extremely efficiently into mechanical energy and delivers massive torque right from a standstill – and at very low speeds.
Advantages of Our Radial Piston Motors (Partner of Italgroup)
As a partner of the renowned manufacturer Italgroup, we offer you motors based on years of development expertise. The radial piston motor solves problems where other motors fail.
Your technical advantages at a glance:
- Enormous Torque: Maximum power delivery directly at start-up (high breakaway torque).
- Jerk-free Start: Thanks to the radial piston arrangement, the motor starts silky smooth even under load.
- Robust Efficiency: Minimized friction losses ensure high efficiency and reduce energy consumption.
- Flexibility: Problem-free reversal of rotation direction for forward and reverse running drives.
Typical Areas of Application for the Radial Piston Motor
Due to its compact width and enormous power density, the radial piston motor is indispensable in heavy industry and the mobile sector:
- Mobile Travel Drives: Direct integration into the wheel hub of forklifts, wheel loaders, and road rollers.
- Heavy Industry & Mining: Drive of crushers, mills, and heavy conveyor systems.
- Maritime Applications: Use in shipbuilding and offshore areas (e.g., winches), where robustness against saltwater and harsh conditions counts.
- Municipal Technology: Precise drives for cleaning vehicles.
Selection Criteria & Technical Data
Selecting a radial piston motor requires a precise analysis of the load cycles.
Pay attention to the following key values during configuration:
- Torque Requirement: How much force (Nm) is required when starting under load?
- Speed Range: Radial piston motors
