Motion requirements & engineering challenges

What the Application Requires from the Drive System

A credible selection begins with the real operating duty. These inputs determine continuous rating, peak capability, technology choice and the level of integration required.

Suitable technologies & solution architecture

Engineer the Complete Motion System

Mobility equipment is developed around the person, supported load and operating route. Motor, gearbox, brake, wheel, controller and battery are sized together to deliver controlled movement and safe stopping.

01

Mobility drive platform

PMDC, brushless, transaxle or integrated wheel-drive solutions are selected from supported mass, wheel torque, speed, gradient and manoeuvring duty.

02

Transmission and brake

Reduction ratio, differential behaviour, wheel diameter, shaft loads, brake holding and manual release are matched to the mechanical layout and safe operating behaviour.

03

Battery and user control

Voltage, peak and continuous current, acceleration, speed input, current limiting, feedback and fail-safe signals are coordinated with the user interface.

04

Comfort and route validation

Noise, vibration, stopping, range, thermal capacity, ingress and repeated route cycles are checked under representative load and operating conditions.
