Initially the ABB Ability™ Smart Sensor solution’s will be released for standard three-phase LV squirrel cage induction motors only. Therefore the sensors should only be mounted on motors that are directly connected to a standard fixed frequency 50/60Hz power supply (DOL, across the line) or started using a Softstarter. Further the motors should be operated in continuous (S1) duty.
Recommended motors for 1st release:
- Standard 3-phase LV induction motors
- DOL / Softstarter, S1 operation
- Frame material of the motor can be cast iron, aluminum or steel
- Finned frame, TEFC
- Frame sizes: 140-440 NEMA, 160-450 IEC
Functionality and compatibility of early releases:
First release: The sensors are initially available as retrofit kits for already installed IEC motors (in limited quantities). They will then be introduced as a factory-fitted option on severe duty NEMA motors manufactured by Baldor, ABB’s unit in the US, and supplied via distributors in North America. In the next stage the sensors will be available as a factory-fitted option on certain IEC motors. The sensors are compatible with standard cast iron fin cooled induction motors in frame sizes 140-449 (NEMA) and 160-450 (IEC) that are connected Direct-On-Line (DOL) and operate in continuous duty (S1). The solution uses a smartphone to relay data from the sensor to the internet. Parameters monitored are surface temperature, bearing condition and overall vibration.
Later releases: Compatibility will be expanded to cover other motor types, DOL intermittent operation, and VFD (variable frequency drive) controlled motors. The range of monitored parameters will be increased on a staged basis to cover the full list shown above. A dedicated gateway will be introduced for automated data communications between the sensor and internet, eliminating the need to periodically pass by with a smartphone to collect the data.
