Frequently Asked Questions
What is direct torque control?
Direct torque control is an advanced motor control method that provides fast torque response without requiring complex coordinate transformations.
What are the benefits of direct torque control?
Fast response to torque and flux reference changes
High efficiency with minimized switching losses
No overshoot in step response
Simplified control without PI current controllers
Automatic compensation for DC circuit voltage variations
Low audible noise due to random switching nature
What type of motor is compatible with inverters?
Three phase AC induction motors are compatible, preferably inverter-grade motors with appropriate voltage insulation (800V for 200V class or 1600V for 400V class inverters).
What are common reasons for motor failure?
According to industry studies, 41% of motor failures are bearing-related, 37% stator-related, 10% rotor-related, and 12% other causes.
How do you select a VFD?
Select based on motor specifications, application requirements, and environmental conditions. Consider voltage class, power rating, control features, and protection requirements.
