Motor Sizing
Load carrying capacity
Wheel offset
The load carrying capacity of the motor is defined by the offset value (a) of the wheel
rim and the application specific safety factor.
The offset value is the distance from the wheel center line (CL) to the motor shaft
interface. The load charts of the motors are given as a function of offset value. The
given load curves refer to the average wheel load on a single motor.
