Product Information

TFDW Single Phase Brushless AC Alternators.

A range of quality brushless, four pole, rotating field dual voltage 115/230V single phase alternators available in a range of sizes and prices, so you can find the configuration that works best for your application.

The wide range of power ratings available in this range of alternators make them ideally suitable to operate as a primary AC power source for standard electrical lighting, household appliances, and general small scale residential use as well as semi commercial.

These units provide self excitation / regulation and a stable output with the use of a quality solid state automatic voltage regulator. This simple system minimizes the complexity and has proven reliable in operation. This range of alternators are designed for continuous duty operation within their power ratings. When driven at a constant rotational speed of 1500 rpm they generate current at a constant AC voltage and frequency. The internal connections may be changed to provide either 230V or 115V AC. Conversion between nominal voltages is simply a matter of changing contacts on a terminal strip inside the terminal box. These alternators may be coupled to a prime mover (driving engine) either by a direct shaft to shaft coupling or by conventional belt and pulleys. The AC frequency of the output power is determined solely by the speed of rotation of the prime mover, the alternators must spin at 1500 RPM to generate 50Hz power. They can be driven either clockwise or anti clockwise to suit your application.

For your safety and piece of mind the TFDW range of alternators are CE approved, comply with International standard: VDE0530, IEC34, NEMA MG1 are manufactured to IP21 protection standard and have dynamically balanced rotors to BS 55625 grade 12.5.

Please note that the standard shipping cost of £39.99 applies to mainland UK only, if you are overseas please contact us for a quotation.

These alternators are not suitable for grid connected applications without the use of a grid tied invertor. We are often asked the question "what size alternator can i couple to my engine" the following may be of some help. As a rule of thumb, at 100% efficiency (which is an impossibility), each BHP is 746 Watts, so a 6 HP engine can theoretically develop 4.476 KW. Practically, there are losses in the alternator/generator, belts, bearings, etc. and the net output power is about 2/3 of the theoretical maximum. So figure 1/2 of the BHP is the number of KW you can realistically expect.

6 BHP from a 6/1 CS engine should yield 3 KW, a 12/2 CS should run 6 KW. Generators and alternators should be specified a little oversized (it improves efficiency and allows for starting surges) and energy stored in the flywheels will help start motors, if not too big and not too often. Compressors without pressure releasers will be very hard to start, fans will be very easy. Several small, hard to start motors will work better than a single large hard to start motor as long as the motors do not try to start at the same time. A voltage/current sensor can be set up to allow a motor to start only when the generator load is low enough.
