4-2-2 Shaft characteristics
There is a limit to the load that can be applied on the motor shaft. Make sure that the load applied on the
radial direction, when mounted on the machine, is below the tolerable values given below. These loads may
affect the motor output torque, so consider them when designing the machine.
