Rotating machinery

We are able to design, develop, review and optimise rotating machinery suited to your application, ranging from a few Watts to many tens of kiloWatts.  Our optimisations depend on your application and product requirements.  Whether designing the complete machine to component level from first principles, identifying a reliable low cost alternative, reviewing your existing technology or working with your team to assess technology options we have in depth design experience with the following ac and electronically commutated topologies:

• Permanent magnet synchronous motors
• Single phase ac asynchronous capacitor run induction motors
• Three phase ac asynchronous induction motors
• Single phase ac asynchronous shaded pole induction motors
• Synchronous motors
• Switched reluctance motors
• Separately excited synchronous motors
• External rotor configurations
• Internal rotor configurations

Working from first principles, our approach is to calculate, review, assess, test and demonstrate using theory and best practice to give you the confidence that solutions are optimal and have known performance boundaries that suit your needs.  These range across the interactive spectrum of efficiency, acoustics, vibration, power density, ratings, legislative compliance, environmental influence, reliability, risk and life cycle in application.

Controls

Our experience ranges from system design through to schematic creation, component selection, specification, printed circuit board layout and all stages supporting this.  From analogue and digital design, component level analysis through, system architecture through to embedded solutions and code written in C or assembler, we are able to take products from concept through to volume production.  We take pride in our design for manufacture approach from the start of any project.  Our extensive standards knowledge for EMC and LVD compliance means that we build in critical characteristics from the start.  Whether designing from first principles, identifying a reliable low cost alternative to an existing design, working with obsolescence, reviewing your existing technology or working with your team to assess technology options we have in depth design experience across the following disciplines:

• Schematic design and printed circuit board layout (we use Pulsonix software)
• Analogue and digital circuit design for low cost, low noise and high performance
• Embedded controls and associated software written in C or assembler as required for system performance
• Switch mode power supply design and associated magnetic components
• Open and closed loop stability in both the analogue and digital domain
• Circuit design, filter implementation and board layout for emission and immunity compliance in high performance environments
• Low voltage and high voltage criteria for component selection, implementation and testing
• Functional and component level test requirements and associated design implementations
• Graphic display implementations (LED, LCD and panel)

Working from first principles, our approach is to calculate, review, assess, test and demonstrate using theory and best practice to give you the confidence that solutions are optimal and have known performance boundaries that suit your needs.  We are directly supported by many of the major semiconductor manufacturers and are able to call on their support as required to ensure optimal designs are followed through to production.

Power electronics and motor drives

Our power electronics experience covers such diverse fields as power factor correction, inverters for off line lighting and uninterruptible power supplies, hybrid converters, topologies for single phase electronically commutated motors through to multi phase vector controlled motor drives for induction, switch reluctance and permanent magnet synchronous machines.  With systems ranging from a few Watts to tens of kiloWatts designs are optimised for the application and assessed to component level.  Whether designing from first principles, identifying a reliable low cost alternative, reviewing your existing technology or working with your team to assess technology options we have in depth design experience with the following:

• Schematic design and printed circuit board layout for power electronic circuits (using Pulsonix software)
• Circuit design, filter implementation and board layout for emission and immunity compliance in high power envronments
• Open and closed loop stability in both the analogue and digital domain
• Single phase and three phase vector control implementation both analogue and digital domains, including space vector modulation approaches and sensorless algorithms
• AC and DC power converters with associated magnetic and planar magnetic component design
• MOSFET, IGBT and bipolar power stages with associated isolated and non-isolated gate drives
• Power factor correction and sinusoidal waveform control in both the analogue and digital domain
• Measurement circuits and safe probing in the high voltage, high power environment
• Isolated and non-isolated converters

Working from first principles, our approach is to calculate, review, assess, test and demonstrate using theory and best practice to give you the confidence that solutions are optimal and have known performance boundaries that suit your needs.  We are directly supported by many of the major semiconductor manufacturers and are able to call on their support as required to ensure optimal designs are followed through to production.

High voltage pulse technology

With experience in the design of equipment related to electric fence energisers, high voltage pulse forming and system fault detection we feel that we are well qualified to design, develop, review and optimise safe systems that incorporate technology suited to the application.  Ranging from fractional Joules to tens of Joules our optimisations depend on the application and product requirements.  This is a rather specialsed area where we have in depth design experience with the following:

• Schematic design and printed circuit board layout for systems operating up to 20 kV (using Pulsonix software)

Partnerships

To run our business effectively, we value our network of partners that enable us to deliver products and solutions to our customers in time frames that meet our needs.  We are an agile business and choose our partnerships carefully since these need to be able to support our vision in the way that we support our customers; with honesty and integrity.  Our CAD systems and component suppliers are core to this so we are proud to provide links (please see our links page) and to represent them as follows:

• Pulsonix
• Visiativ (Solidworks)

Without our chosen partners, we would not be able to support our customers.  Our priority is to be seen by our customers as their chosen partner.
