Characteristic of Brushless Electric Motor
1. It can replace DC motor speed regulation, frequency
converter+variable frequency motor speed regulation, and
asynchronous motor+reducer speed regulation.
2. It has the advantages of traditional DC motors, while also
eliminating carbon brush and slip ring structures.
3. It can operate at low speed and high power, eliminating the need
for the gearbox to directly drive large loads.
4. Small size, light weight, and high output.
5. Excellent torque characteristics, good torque performance at
medium and low speeds, high starting torque, and low starting
current.
6. Stepless speed regulation, with a wide speed range and strong
overload capacity.
7. Soft start, soft stop, and good braking characteristics can
eliminate the need for existing mechanical or electromagnetic
braking devices.
8. High efficiency, the motor itself does not have excitation
losses and carbon brush losses, eliminating multi-level
deceleration losses, and the comprehensive power saving rate can
reach 20%~60%.
9. High reliability, good stability, strong adaptability, and
simple maintenance and repair.
10. Resistant to bumps and vibrations, low noise, low vibration,
smooth operation, and long service life.
11. It does not generate sparks and is particularly suitable for
explosive locations, with explosion-proof type.
12. Select trapezoidal wave magnetic field motor and sine wave
magnetic field motor as needed.
Model Selection
The main parameters to refer to when selecting brushless DC motors
are as follows:
1.Maximum torque: it can be obtained by adding the load torque,
Moment of inertia and friction. In addition, there are some
additional factors that affect the maximum torque, such as the
resistance of air gap air.
2.Square modulus torque: it can be approximately considered as the continuous output torque required for practical application, which
is determined by many factors: maximum torque, load torque, Moment
of inertia, acceleration, deceleration, operation time, etc.
3.Speed: This is the speed that has application requirements, and
the speed demand of the motor can be determined based on the
trapezoidal curve of the motor speed. Usually, a 10% margin should
be left in the calculation.
