Frequently Asked Questions
What are the benefits of direct torque control?
  • Fast torque and flux adjustment through reference changes
  • High efficiency with minimized switching losses
  • No overshoot in step response
  • No dynamic coordinate transforms required
  • No separate modulator needed
  • No PI current controllers or tuning required
  • Low audible noise operation
  • Automatic compensation for DC circuit voltage variations
What type of motor is compatible with inverters?
The inverter requires a three-phase AC induction motor. For optimal performance, use an inverter-grade motor with 800V insulation for 200V class inverters or 1600V insulation for 400V class inverters. Always match the motor size to your application requirements before selecting an inverter.
What are common reasons for motor failure?
According to industry studies, motor failures are typically caused by: 41% bearing issues, 37% stator problems, 10% rotor failures, and 12% other causes.
