Frequently Asked Questions
What is direct torque control?
Semi-Automatic PET Bottle Blowing Machine Bottle Making Machine Bottle Moulding Machine PET Bottle Making Machine is suitable for producing PET plastic containers and bottles in all shapes.
What is the benefit of direct torque control?
Torque and flux can be changed very fast by changing the references
High efficiency & low losses - switching losses are minimized because the transistors are switched only when needed
The step response has no overshoot
No dynamic coordinate transforms are needed, all calculations are done in stationary coordinate system
No separate modulator is needed, the hysteresis control defines the switch control signals directly
There are no PI current controllers, thus no tuning of the control is required
The switching frequency of the transistors is not constant but can be controlled
Due to the hysteresis control the switching process is random by nature, resulting in low audible noise
The intermediate DC circuit's voltage variation is automatically accounted for in the algorithm
Synchronization to rotating machine is straightforward due to the fast control
What Type Of Motor Is Compatible With Inverters?
Inverter motor type must be a three phase AC induction motor. Preferably, you should use an inverter-grade motor that has 800V insulation for 200V class inverters, or 1600V insulation for 400V class inverters. For motor size, in practice it is much better to find the right size motor for your application; then look for an inverter to match the motor.
What Are Some Of The Common Reasons Why Motors Fail?
The EPRI Power Industry Study by General Electric in 1985 offered the following causes based on 6,000 utility motor failures: 41% were bearing related, 37% were stator related, 10% were rotor related and 12% were other causes.
