accurate shaft power monitoring
The Emotron Shaft Power Monitoring Technology offers very accurate, reliable, and cost-efficient supervision of electric motor-driven processes. It was patented in 1979 and since then has been the basis for our shaft power monitors as well as a unique integrated feature in our drives and soft starts.
Patented calculation technique
The patented technique monitors the shaft power of the motor driving the process or machine. This is done by measuring motor input power and subtracting the motor power loss calculated using a precise algorithm. The result is a correct and linear motor load value across the entire load range. Any deviation from the set load levels will immediately cause the monitor to initiate a warning or stop the machine. The shaft power is indicated as a percentage of rated power, kW or HP.
four levels of protection
The M20 Shaft Power Monitor offers four levels of protection; underload pre-alarm, underload main alarm, overload pre-alarm, and overload main alarm. These levels can be adjusted – independently of one-another – so as to ensure an experience that is fully-customizable, offering complete protection of the driven equipment.
