Efficient wheel hub motor for autonomous industrial trucks

Rigid, stationary transport devices such as conveyor belts are used in the today Intralogistik increasingly through autonomous transport units or Automated Guided Vehicles (AGV) replaced. For economic operation you need powerful, compact drives with a long service life. Heinzman and Framo Morat have a new one for this hub motor Developed with integrated gear.

From the Motor about the Transmission, the output shaft through to the bearing, all components of the PMSG 066F-060 drive planned as a unit in a common housing. This resulted in an extremely compact and robust solution.

Even in rough driving conditions up to 500 kg per wheel or 5000 N can be implemented. With an axial length of just 110 mm and a wheel diameter of 160 or 200 mm, the self-cooled weighs Power Type only 7,5 kg.

In Degree of protection IP67 the wheel hub motor is suitable for all areas of intralogistics. The electric drive is equipped with one or two-stage gears. With a ratio of 1:32, the maximum drive torque is up to 120 Nm with a service life of 20.000 hours.

Technical features of the wheel hub motor

A matched to the wheel hub motor Two-channel motor controller controls up to two drive wheels. The steering works via different speeds of the wheels. Electric differential, torque vectoring and recuperation are standard. The individual programming of the controller and customer-specific equipment e.g. B. with additional mechanical locking or operatingbrake or high-resolution encoder are possible.

They are also available to adapt the wheel hub motors to the application 24, 36 and 48 V supply voltage with an output of 0,4 kW per motor. The nominal speed of the wheel hub motors of 1500, 3000 or 4500 min^-1 reduces the one or two stage planetary gear with reduction between 1:4 and 1:32 so that up to 120 Nm nominal torque is transmitted to the wheels on the output shaft.
