4000W Low Interference 25Nm Outer Rotor Brushless DC Motor
Description
Brushless DC motors consists of the motor body and controller, is a
typical mechatronic products. Because brushless DC motor is running
self-controlled, so it does not like synchronous motors under heavy
starting with frequency conversion to variable speed, which is
added starting additional winding on the rotor, and it will not be
out of step and oscillate at the time of mutation load. The
permanent magnet of small and medium-capacity brushless DC motor is
always more high energy product rare earth neodymium iron boron
(Nd-Fe-B) materials. Thus, the volume of rare earth permanent
magnet brushless motor is far smaller more than the three-phase
asynchronous motor with same capacity.
Brushless DC motor has the DC brush motor characteristics and the
frequency change devices, so they are called DC frequency
conversion, the international generic term is the BLDC. The
operating efficiency, low-speed torque and speed accuracy of
brushless DC motor is better than any inverter control technology.
advantage of the brushless motor
1. Brushless, low interference
Brushless motor eliminates brushes, the most immediate change is
that there is no spark generated when the motor is running, thus
greatly reducing the spark radio interference.
2. Low noise, smooth operation
Brushless motor has no a brush, the friction is greatly reduced in
running, and smooth operating; noise will be much lower, this
advantage is a huge support for the model running stability.
3. Long life, low maintenance costs
There is no brush, so the main loss of brushless motor is from the
bearing, at the mechanical point of view, the brushless motor is an
almost none maintenance electric motor, and when necessary, you can
only clean some dust.
Features
1, widely power range: Our Company can provide 5W - 200KW brushless
DC motor,
2, the unique non-magnet technology: the above 5KW power motors are
applied the International leading of non-magnet technology to solve
the electromagnetic eddy problems in high-power motor, reducing the
motor heat and energy consumption, efficiency is improved 30 %.
3, cost advantage
4, powerful development capabilities: we have fifteen years of
experience in R&D and production of brushless motor, with
profound technical background.
5, flexible customization capabilities
6, the highest sealing rating: IP67
The application of scope
Usually used in the equipment with high control requirements and
high speed, such as model of aircraft, precision instruments and
other device with strict control of the motor speed, so it was only
the use of high-end equipment.
Long life:
Usually the service life is at tens of thousands of hours, the life
time of various brushless motors changes with different bearings of
BLDC. Conventional brushless motor life is ten times more than
ordinary motor.
Effect:
Usually brushless motor is digital frequency controlled, It can be
very easy to implement from a few turns per minute to turns tens of
thousands per minute.
