In some projects like e.g. Automated Guided Vehicles (AGV) there is limited space available for the drive motors, especially in the axial dimension. For such cases, flat motors are required. Our in-wheel XR series is a permanent magnet brushless motor with an external rotor. Permanent magnet brushless motors are generally the most efficient and highest torque density motors available today. The XR series gains from two distinct additional advantages: the magnets are positioned on an externally running rotor which gives the motor the fundamental geometric advantage that torque is being delivered on the outer-most point of the motor. Finally, the torque density of the XR series is maximised by a high degree of slot fill. The high slot fill is achieved by winding each of the stator teeth individually before assembling them together into a stator.

The stator teeth of the XR series are modular and interlock in such a way that we can vary the diameter and length of the stator more or less infinitely to fit both the packaging and the power requirements of the application.  The in-wheel XR series can be liquid cooled or even oil filled for subsea applications that require underwater pressure compensation.

Applications for the XR Series in-motors include substitution of large high torque hydraulic actuation systems with a compact efficient motor, industrial and marine winch systems, propulsion of bomb disposal robots and other specialised military electric vehicles and trailers, traction for commercial electric vehicles for example in mining, direct drive radar systems, direct drive railway vehicles, compact generators for auxiliary power units, and general hybridisation of vehicle propulsion systems.

In-Wheel Motor XR15-05e for applications in intralogistics

The XR15-05e In-Wheel Motor is an external rotor motor and was designed as a direct drive without gearing. It is designed with a low axial length (<50mm) and a high power density. With this motor, nominal torques of 8Nm and a nominal speed of up to 480U/min can be realized. The XR15-05e is provided with an integrated magnetic encoder (angle encoder) for precise position detection or speed control. The motor is operated with 36-60Vdc. Seals between the rotating rotor and the mounting flange or stator prevent dirt and moisture from entering. The motor's built-in angular contact ball bearing provides optimum support for high axial and radial forces. The In-Wheel Motors of the XR15 series are optimized for application in Automated Guided Vehicles (AGV), industrial robots and intralogistics.
