Abstract
1288831 Control of motors J PERTHEN 25 Feb 1970 [26 Feb 1969] 9202/70 Heading H2J A motor M drives means for moving a sensing element A relatively to a workpiece whose surface area is to be measured, the speed of the motor being kept proportional to a reference voltage from source S by regulator R. The reference voltage is also applied through integrator I to trigger circuit T, the output voltage of the integrator being proportional to the distance travelled by the motor in a given time. The signal from the trigger circuit may be used to stop the motor, initiate its reversal, or control computing circuits. The threshold voltage of the trigger circuit, and the time constant of the integrator are adjustable. The motor is of the D.C. shunt-wound or of the A.C. type.
