MEDIUM VOLTAGE DRIVE STARTER
TYPE MV-SVFD-ML1
UP TO 20 MW
UP TO 12 KV
UP TO 520/2500 A
MOCOTECH
PRESENTS THE
VARIABLE
FREQUENCY DRIVE
STARTER TYPE
MV-SVFD & VFD
CUSTOMER ADVANTAGES
· Up to 520 A output and 2500 A by-pass current at 2,3 – 11 kV
· Starting current ≤ rated motor current up to rated motor torque
· Starting current is a fraction of motor current at reduced load
· No need to oversize feeding transformers or generators
· No starting related voltage drop in the power supply
· Synchronized by-pass control
· Zero active power losses after by-pass closed
The MV-VFD is based on multi
level voltage source inverter
technology for continuous operation
and designed as MV-SVFD for short
time operation.
Drive starter applications:
· Starting of standard asynchronous
and synchronous motors.
· Retrofit to any existing inductionand wound rotor motor.
· Improves efficiency – saves operation cost
· Perfect sinusoidal waves
· No harmonic filter required
· Minimum common mode voltage to motor winding
· Negligible torque ripple, noise and heat caused by harmonics
· Min. du/dt and di/dt – very low EMI
· Long motor cables possible
· PWM based U/f also called VVVF control
· PWM based vector control incl. field orientation control
· Open and closed loop control
· Increases lifetime of drives and machines
· Highest availability and operation stability
· Cost saving compact modular design with many options
· All equipment available in the drive starter, ready for operation:
The highly sophisticated
· Input contactor
VFD guarantees a very smooth
· Output contactor
continuous speed control and
· By-pass contactor
step-less acceleration without
· Multi level phase shift input transformer
any mechanical shock to the motor
· Starting power electronics
and the load (if used as SVFD drive
· HMI + central controller + PLC for starting control
starter until full speed and the by-
· Totally digital controlled with self-test diagnostic function
pass is closed).
· Many acceleration/starting ramps possible
· Soft start/stop function with lowest mechanical stress
· Load dependent calculated starting voltage and current
· Inductive full load test before delivery
