Sailability Forum UK: new forum reply to Solid State Motor Drivers

New reply from Spike Spencer

<p>Thanks for the positive feedback Simon, that's reassuring.  However, even critical feedback is useful to improving the breed and design maturity.</p>
<p>My advice for routine maintenance is to apply electrical contact grease to the connectors <em>(system connectors outside the electronics box)</em> after immersion/drying, or at least annually.  See original description in "Connectors" thread for type and supplier,</p>

<p>RAE Farnborough 'Magic Fix' for experimental equipment = Undo all connectors and lubricate/grease.  Reconnect and the problem frequently goes away.</p>
<p>The worst type of fault is "No fault found" at the workbench !  </p>

Solid State Motor Drivers

<p>As promised, the attached essay is my account of the developments made at New Forest & District Sailablity for several sailors over the last 10 years after I tired of repairing standard equipment.  Prototype was proved by Keith Harris at the HANSA Nationals held at WPSA in 2014 and it continued in use for the following 2 seasons.  The current version of this equipment now resides in David Durston's LIBERTY.</p>
<p>Anyone who is a professional Electronics Engineer will undoubtedly have comments and I welcome any observations or inputs for future improvement.  I am only an Electronics hobbyist myself who started in the era of valves and magnetic amplifiers where my professional colleagues still chanted "Tune for maximum smoke"  (If it works, don't knock it !)</p>
<p>I hope this is of interest to the community.</p>
