DEVICE FOR AUTOMATIC CONTROL OF LOAD AT METAL CUTTER MOTOR SHAFT Russian patent published in 2013 - IPC B23Q15/00 

FIELD: process engineering.

SUBSTANCE: invention relates to metal cutters, particularly, to automatic control of their drives. Proposed device comprises current transducer 1, voltage transducer 2, romp transducer 3, multiplexer 4, ADC 5, arithmetic device 6, memory controlled element 7, and motor rpm setting device 8. Output of current transducer 1 is connected with first input of multiplexer 4. Output of voltage transducer 2 is connected with second input of multiplexer 4. RPM transducer is connected with third input of multiplexer 4. Output of multiplexer 4 is connected with ADC input. ADC output is connected with first input of arithmetic device 6. Output of memory controlled element 7 is connected with second input of arithmetic device 6 while its input is connected with first output of said arithmetic device second output of which is connected with input of setting device 8.

EFFECT: increased quality of control, simplified wiring.
