Brushless Direct Current (BLDC)
motors are one of the motor types rapidly gaining popularity. BLDC motors
are used in industries such as Appliances, Automotive, Aerospace,
Consumer, Medical, Industrial Automation, Equipment and Instrumentation.
As the name implies, BLDC motors do not use brushes for commutation;
instead, they are electronically commutated.
BLDC motors have many advantages
over brushed DC motors and induction motors. A few of these are:
Better speed versus torque characteristics, High dynamic response,
High efficiency, Long operating life, Noiseless operation,
Higher speed ranges.
A brushless motor is constructed
with a permanent magnet rotor and wire wound stator poles. Electrical
energy is converted to mechanical energy by the magnetic attractive forces
between the permanent magnet rotor and a rotating magnetic field induced
in the wound stator poles .

The TC647 is a combination proportional brushless DC (BDC)
fan controller and fault detector. Individual TC647s are driven by a
common input signal. Normally, the circuit labeled “Unit 1” is in service
and provides proportional speed control for Fan 1 based on the VIN input
voltage. During normal operation (Fan 1 rotating), Unit 1's FAULT line is
high, causing Q2 to pull the VMIN2 node of Unit 2 low. This causes the
TC647 in Unit 2 to be in shutdown mode.
State-of-the-art sensorless BLDC motor control technology
provides performance on par with conventional hall sensor commutated
drives in non-servo applications. Cost reductions of motor materials and
electronic components, along with the reduced wiring and hardware
simplicity of “Ping Method” sensorless controls, are making BLDC motors
and drives a superior choice in commercial applications where energy
efficiency or motor-frame size are of primary importance.
Technology is used in the development and research of power
electronic products. The reason is that main power energy comes from
electricity, no matter in our daily life or production equipment in
business. It needs to transfer electric energy into variety energy in
application. That is the importance of power electronic technology for
the spirit of 3MEN. At 3MEM, our outstanding team is to revolutionize the
industry with user-friendly product design and keep a leading research and
promotion in this field. Our goal is to provide you cost effective
products with unsurpassed performance to help you enhance your advantage
in the competitive market.
find its application in: High rpm applications, Light weight applications,
Low thermal emission applications.
are several options available to the manufacturer and user regarding the
type of variable speed drive to use on the Extruder and rotating mold
applications of the blow molding machine, there are some distinct
advantages in the use of the Brushless D.C. drive while other types of
drives may become available in the future that may provide these
advantages, they are not yet available for general use in the HP sizes
necessary for most blow molding machines. The Brushless DC technology is
here and in wide use in various extrusion and related applications in the
