According to the control system, it can be divided into 1, frequency conversion system tensile testing machine: the frequency conversion motor control system is adopted, and the tensile and compression speed is controlled
by the frequency conversion governor.
2, servo system tensile testing machine: the use of servo motor control system, tensile, compression speed and displacement control is more accurate
.
The servo motor system is a servo control system, which adopts intelligent feedback operation, which can be tested at fixed speed, cycle test, programming test, etc
.
3, other driving method tensile testing machine: through the DC motor control, the drive mode of tensile testing machine due to low cost performance, has been gradually eliminated
.
