Compact drive system for AGVs / AMRs

The drive system manufacturer HEINZMANN has introduced a new wheel hub motor with integrated transmission, which was developed in close collaboration with Framo Morat. The compact, high-performance drive provides ensures efficient operation in automated guided vehicles (AGV) and autonomous mobile robots (AMR). Since all components of the drive—from the motor and transmission to the output shaft along with the bearing—have been integrated in one housing as a unit, the solution is extremely compact and robust. It has an axial length of just 110 mm at a wheel diameter of 160 or 200 mm, which provides a space-saving and self-cooled drive unit weighing only 7.5 kg. Even during rough operation, each wheel can handle up to 500 kg (5000 N). The compact drive system is equipped with one- or two-stage transmissions and, at a gear ratio of 1:32, delivers a maximum drive torque of up to 120 Nm. The robust design of the motor and transmission guarantees a service life of 20,000 hours. Thanks to the IP67 protection class, the drive system is suitable for all areas of intralogistics and robotics.

A two-channel motor controller that is perfectly matched to the system controls up to two drive wheels. The steering function is enabled by the different speeds of the two drive wheels. Electrical differential, torque vectoring and recuperation are standard with this system. Customer-specific programming of the controller is possible, as is customized equipment of the drive, for example, with an additional mechanical parking or service brake, a high-resolution encoder and much more.
