What is
a Hybrid Brushless Motor?
All power drive current to
this motor is brushless: drive current passes only through the stator and
does not go through any brushes. Only a small field current passes through
brushes and smooth slip rings to the rotor. This is a highly reliable
design with minimal abrasion (unlike commutators in conventional dc
motors) which is typically used for resolvers and synchros on aircraft and
high-reliability industrial applications. This is called a Hybrid Brushless
Motor since it has a combination of brushless power drive current and a
small brushed field current
This Hybrid Brushless Motor is functionally the same as a conventional
brushless motor except that it has an adjustable field, unlike a
conventional brushless motor, which has a fixed field. This field is
adjusted by applying a small dc current, typically 0.5A – 3.0A. This can give
better performance than a conventional brushless motor by producing high
torque at BOTH low speeds and high speeds, compared to a conventional
brushless motor which tends to lose torque at high speeds.
An automotive alternator converted to a motor can exceed the performance of
both brushed and
conventional brushless motors because of the combination of its brushless
drive current and adjustable field. A car alternator changed over to a
motor can put out in excess of 1.0 HP -- in some applications far above that,
depending on the alternator, how it's converted, and how it's controlled.
An
automotive alternator converted to a motor is much less
expensive than a conventional brushless motor with the same power output.
A car alternator that can be readily converted to a powerful motor costs about $100.00, but a conventional
brushless motor that produces about the same power output typically costs far more -- well over $500.00
and is often more difficult to obtain with long order lead times.
In
addition, a car alternator functioning as a motor has more versatile control than a conventional
brushless motor, and it can have much more power and torque at high speeds
than a conventional brushless motor of similar size due to its adjustable
field.
Our Alternator Conversion Manual, "How to Convert an Automotive
Alternator to a Hybrid Brushless Motor" shows in clear step-by-step
instructions with
photographs how to do
the conversion. It also explains how to drive the alternator as a motor.
It includes common-sense explanations of how the converted alternator
functions as a motor with clear, easy-to-read diagrams.
After reading our how-to guide, you will be able to
convert a car alternator into a powerful, reliable, and low-cost Hybrid
Brushless Motor using low-cost, common tools, and you will understand how
this new motor works and the advantages this new motor has over
conventional brush and brushless motors.
(Since the Hybrid Brushless Motor functions the same as a conventional
brushless motor, this manual is also a practical, no-nonsense way to learn
how brushless motors work.)
What can you use this Hybrid Brushless
Motor for?
-- anywhere a powerful, low-cost, high-reliability motor can be used:
industrial, electric vehicles, alternative energy applications (converting
gasoline, diesel, pneumatic, and hydraulic machinery and equipment to
electric) robotics, model aircraft, scientific, automotive, aircraft,
marine, and scores of related applications.
This provides a reliable and low-cost
alternative to high-power brushless motors which is easily acquired and
second-sourced.
