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

Off-highway motion is developed around terrain, payload and the full working cycle. Traction and auxiliary systems must remain dependable under shock, contamination and changing mechanical load.

01

High-torque drive platform

Traction motors, transaxles and gearmotors are selected from vehicle mass, terrain resistance, gradient, wheel size, speed and overload events.

02

Mechanical and auxiliary integration

Axles, reduction, bearings, brakes, hydraulics, cooling and powered working functions are reviewed as one mobile equipment system.

03

Power and control architecture

Battery or generator supply, current demand, feedback, communications, protection and safe stopping are matched to the machine controller.

04

Environmental validation

Thermal duty, shock, vibration, ingress, dust, moisture, corrosion and representative working cycles are verified before production release.
