Of course you know about the amazing, low cost brushed motor that Briggs & Stratton developed many years ago – the Etek. John Fiorenza, former principal engineer for B&S also developed a brushless (permanent magnet synchronous) version. It is capable of producing up to 15 HP (6 HP continuous). It has a stationary three-phase motor winding, with a very simple permanent magnet rotor – and no brushes to wear out! The stationary windings, or stator, consist of copper coils placed in a laminated steel core. This is unlike other brushless motors in use because the steel core is not made of individual laminations pressed into a motor shaft. "This motor uses a continuous strip of steel, wound like a roll of tape” says Mr. Fiorenza. We say “Rock on, John!” – and thanks for such an awesome bit of engineering!

We have a quantity of these available for immediate shipment, all new in the box.

Commutation of the motor is through hall effect sensors with an absolute maximum of 4,000 RPM. If you’re not familiar with brushless motors, you cannot just hook them up to DC and make them spin – you need a real three phase brushless controller (one of which we sell below). Each motor contains a serialized dyno plot (there is an example above in the list of supporting documents). We also sell a nifty mount so scroll down for more information.

This is the perfect mate to our brushless “Etek” motor, above. It operates at 24-36V and includes a ton of safety settings.

Here are the specifications:
	24-36V input
	250 amp continuous rating
	Torque or RPM mode servo operation
	93% efficient
	20 pin connector in Molex "MiniFit Jr."
	connector - Digi-Key P/N WM3709-ND
	pins - Digi-Key P/N WM2501-ND
	4000 RPM max commutation speed
	Weight: 6.5 lbs. (shipping weight 8 lbs.)

You need to know that this is a microprocessor based controller. So there are a bunch of settings that control various elements of its operation. In the “Supporting Documents” section you will find the reference manual from SEVCON as well as a document that I created, containing all the important settings that I need to put into place before I ship it to you. These are done with a special handheld tool from SEVCON, called a “calibrator.” It’s about the size of a DVM and basically a dumb user interface to the internal menu system in the controller. I bought mine on eBay though you can also order them straight from SEVCON. (In the future I hope to offer a couple to loan out.)

Please note:  This is not a 48V controller.

For us to configure your controller before shipment we'll need you to download our Programming Configuration Worksheet, fill out the required information and email it to us, as an attachment.  Please include your name in the subject line.  If you do not have Microsoft Word, then use this pdf file and fax it to me.

We designed this to mount your brushed and brushless Etek motors in one of two ways:

	Fixed - using the four static bolt holes
	Adjustable - choose the other four and   pivot about one of them to pull tension   on a belt or sprocket.

This unique mount is water-jetted from 3/8" 6061 aluminum and will save you tons of time installing your Etek motor into your project!
