Micro Tractor

As we’re both graduates of Loughborough Uni, Erica & I were delighted to be able to supply a couple of our new Pro-100s for the prototype stage of this micro tractor project.

Warehouse Pallet Shuttle

The guys at Advance Automation Systems doing some testing on this battery powered pallet shuttle for a warehouse. They are using a Pro-360 that is switched between the driving wheels and the two conveyors. We had to do a small change to our software to make it work better with their control panel. 

Hydraulic Pump Control 2

Following on from the successful test of the Pro-360-HC in our workshop the guys at Osbit and Hyserve have now installed it on the crane of this mighty wind turbine installation vessel. It’s being used to fit the yellow turbine jackets onto the sea bed foundations. Each jacket weighs 1100 tonnes. The Pro-360 is driving a hydraulic pump that operates a clamping ring.

Linear Actuator / Servo Control

We were asked if we could add a feedback voltage input to our software so that the controller would respond to the input from a position sensor, the aim being to create a really powerful servo mechanism. We’re pleased to say that we’ve done it, here’s a short video of a very powerful linear actuator behaving just like a radio control servo. This software will be able to go in our Pro-100, Pro-160, and Pro-360 controllers, so if you need a 360A servo give us a call.

Seaweed Farming

Another great project that we’re chuffed to be involved with. The guys at www.SeaweedGeneration.com are farming seaweed to capture and store CO2. We supplied one of our Pro-160s to control the winch on this prototype catamaran in Antigua. Shame they didn’t need on site tech support though!

Turbo Caddy Conversion

Here’s a Turbo Caddy golf buggy in the middle of a controller replacement operation. One of our Pro-160s went in a treat, and the patient is up and running again. We found a design flaw with the original wiring, the battery plugs are not colour coded, it’s easy to reverse them and apply reverse polarity to the electronics!😡

Barbies’ Car

While we can’t be too specific about the details….Some say that Barbies’ car in the latest movie might just be sporting some 4QD gear! All we know is that it’s very pink.

Noise Suppression Case Study

Many of you will know that I tend to bang on about motor noise suppression, my stern lectures are often met with a resigned smile and promises to fit some in the future. Well this week we had a really interesting case that highlighted the importance of taking this seriously.

The Lord Raglan is a tourist boat running on the Brecon Canal. It is unusual in that it has a rudder, motor, and propeller at each end, it doesn’t turn around in the narrow canal, the helmsman just turns off one motor, locks one rudder and goes to the other end to drive back.

It has a single battery bank feeding one Pro-360-HV and Lynch LEM-200 motor at each end. At one end the installation has been fine, but at the other end there have been three controller failures. We spent a day there this week looking to figure out what was causing the problems.

As soon as we opened the engine bay at the problem end the cause was apparent – there were no noise suppression components fitted to the motor. However these were also missing from the other end which did not have problems, so what was the difference?

Looking into the routing of the motor wires we found that they had been run directly on top of the battery wires feeding the problem controller. The motor wires are carrying a large current that is being switched on and off very quickly, this, along with the lack of noise suppression was inducing noise into the battery wires for the controller and causing mosfet latch-up to occur.

The solution was to fit an extra section of trunking to allow the motor wires to be routed away from the battery wires, and also to fit noise suppression components to both motors.

Looking forward to going for a cruise now that it back working as it should.

Yamaha G22 Conversion

The OEM controllers for the Yamaha G22 golf cart have the part number IC3645SH4V262Y1, but these don’t appear to be readily available in the UK. A customer asked us if we could provide a solution, so we looked to see if our Pro-160-HC could be made to work. After some investigation we obtained the matching connector for the wiring harness plug, figured out the various bits and pieces, and created a solution that was pretty straightforward to fit. We’ll have a look at making up a small circuit board that should make it even simpler.

Long Life 50 Degree Potentiometer

You told us that you wanted a 50 degree potentiometer for the RBT that lasted longer than the standard one. We built ourselves a test rig and ran a load of the old design through a range of life tests to get some solid data that we could discuss with the manufacturer. To cut a long story short, the manufacturer has created a new potentiometer design with an improved track layout. We have had these running on the test rig for many 000s of operations now, and the ones we have stripped down show negligible signs of wear. Our tests to establish an exact figure will take some time to conclude but early results are very encouraging, and we are pleased to say that these are now available.

All 50′ pots supplied after 4th May 2023 are the new design, they are marked with a black dot on the rear of the casing.

This picture shows the old [top] and new track designs.
