Machining

The in house machine shop at Electro Tech, Inc. is more than capable of any machining required for the repair of electric motors. We quite frequently sleeve endbells, sleeve bearing journals, turn/undercut commutators, bore and broach keyways, and repair a variety of other rotor problems. The machine shop has over 30 years of experience and meets or exceeds factory tolerances, usually with in .0005 of an inch. Most work is done in either our production lathe with 8ft ways or our Bridgeport mill and then surface ground if needed. Custom fabrication is also available so feel free to give us a call.

Encapsulation

Does your motor run in a damp or wet environment?

It is true that water and electricity DO NOT MIX! And water damage is one of the most common causes of failures in electric motors. Whether it is from a wash-down procedure, periodic coolant baths, or even condensation, moisture is a real problem.

At Electro Tech, Inc. we are fully aware that many motors are in these types of locations and there is nothing the end user can do about it. But there is something we can do about it for you! That is exactly why we offer an encapsulation service for your motor.

Specially formulated two-part epoxy resins are designed to keep the winding and other important electrical components free of water and helps to dissipate heat to the case. We can encapsulate windings, plugs, terminal blocks, brake/magnet coils, and some servo feedback devices. In addition to replacing/adding seals it will greatly increase the life of your motor and in turn lower maintence costs.

Balancing / Vibration

At Electro Tech, Inc. we don't just want to get your motor to run, we want it to run as good as or better than new. Part of how we acheive this is through digital balancing. An unbalanced rotor will cause future failures and might even cause more intricate equipment not to run at all. We primarily use dynamic balancing, which allows for faster and more accurate readings. On site vibration analysis is also available upon request. All balancing is done to ISO G2.5 standards, unless your application requires higher standards, which is not a problem. Although Electro Tech, Inc. as a shop is currently not ISO certified, a computer printout verifying readings and tolerances is available upon request.

Free Evaluation

The full inspection and evaluation of your motor is free upon request. We will first provide you with a detailed quote letting you see what the problem was, and what it will cost to fix it, before beginning the repair.

Time & Material Billing

We do not believe in preset repair pricing. Our time and material billing system ensures both fair competitive pricing and a high quality-to-value ratio repair.

24 Hour Emergency Service

Exactly what it sounds like. You have a problem, call us. We will do everything possible to get you up and running, no matter what time of the day, or day of the week.

Crane Service

We work closely with other businesses in the area to provide a value priced crane service for motors too large to move by hand.

Expert Cross-Reference
