Optimise performance with the right motor and industrial drives.
Selection of the correct motor drive solution is crucial to ensure long term, trouble free performance.
Considerations when selecting a motor drive solution that will provide performance, value, longevity and lowest total cost of ownership include-
- Process / Application
- Motor Technology / Compatibility
- Installation Environment (temperature, conformal coating, IP rating, RFI etc)
- System Efficiency
- Physical size considerations
- Network Impact analysis
- Field bus compatibility
- Dedicated process protection and functionality
At Centralian Controls, we supply motor drive solutions that are optimised to each individual application. Our factory trained engineers review every application, to ensure the right solution is offered to the customer.
We do this in proud partnership with the industry leader in low voltage variable speed drives, Danfoss Drives. Providing 70 years combined experience with VACON® and VLT® brands of AC drives it is easy to see why Centralian Controls is your first choice for motor drive solutions.
For further peace of mind, Centralian Controls, in conjunction with Danfoss Drives Australia, will offer support from, pre sales to commissioning to end of life of the drive and have the facilities to repair and load test failed / damaged drives when the unlikely event may occur.Let's Talk

Due to the internal rectification of AC to DC voltage, Motor drives generate a non-sinusoidal input current. This is known as Harmonic Current Distortion (THDi). The distorted current waveform will flow into the supply impedance and generate Harmonic Voltage distortion (THDv)
Limits are imposed by network suppliers to the level of Harmonic Distortion (THDi or THDv) that a particular installation may contribute to the supply network.
This affect can also cause issues with generators as the current distortion flows through the alternators impedance.
Centralian Controls has experienced engineers who can review your project and recommend the most effective harmonic mitigation solution to ensure any limits are observed. From small IP20 individual requirements to large floor standing IP54 requirements we can offer both 3 and 4 wire solutions.
High peak voltage and extremely rapid voltage pulse rise times cause stress on motor windings and insulation. Modern motor manufacturers are aware of the impact that motor drives have on their products and typically supply products that can withstand these stresses.
However applications involving submersible pumps, long motor cables and older motors require verification that the drive will not cause damage to the motor insulation. If the motor manufacturer recommends protection the following options can be used as appropriate.
dU/dt Filters reduce the rate of voltage rise on the motor terminals and protect old or weak motor insulation against breakdown This can also be particularly important for short motor cables.
Sine Filters smooth the output voltage of a motor drive and reduce motor insulation stress. Bearing currents and noise development within the motor are also reduced.
Common Mode Cores, installed around the three motor phases (U, V, W) reduce high-frequency common-mode currents.
In some instances, a variable speed motor drive may not be the correct choice for the application. Soft Starters provide a comprehensive solution for starting and stopping three phase asynchronous motors.
Integrated current transducers measure motor current and provide important data for optimal motor start and stop ramps. With the options of analogue or micro-processor based controllers we can provide solutions up to 1600A and with built in bypass contactor up to 961A.
