Motornostix sensors are permanently fixed to to the machine in order to measure vibration, acoustic emission (AE) and temperature variations. Typical measurement locations are on the Motor Drive End and Non Drive End, Gearbox Input Drive End and Non Drive End, Gearbox Output and Pinion Drive End and Non Drive End, as well as the Motor Speed and Trunnion bearings.
Failure modes that have been detected on mill installations include:
- Motor - Gearbox misalignment
- Coupling imbalance
- Motor and Gearbox loose foot
- Bearing surface wear
- Gearbox – Pinion misalignment
- Gear surface wear
- Sleeve bearing surface damage
- Pinion - Girth gear surface wear
The Motornostix system has been installed on many ore crushing mills (ball mills, rod mills etc) and successfully used for condition monitoring of these machines.
