You think the motor is
becoming unusually hot
•
It may be overloaded or the rotation speed is too low :
check the current and the operating cycle of the motor.
•
Check if the mounting surface is enough or if this surface
is not a heat source – see §3.6 cooling.
•
Friction in the machine may be too high :
- Test the motor current with and without a load.
- Check the motor does not have thermal insulation.
- Check that there is no friction from the brake when
the brake power is on.
You find that the motor
is too noisy Several possible explanations :
•
Unsatisfactory mechanical balancing
•
There is friction from the brake: mechanical jamming.
•
Defective coupling
•
Loosening of several pieces
•
Poor adjustment of servo drive or position loop : check
rotation in open loop
