DC brushless planetary gear motor XM42BLS
A stepper motor is an electromagnetic mechanical device that
converts electrical pulse signals into angular displacement or
linear displacement. It has the advantages of high precision, high
reliability, and easy control, and is widely used in the following
fields:
Industrial automation and CNC machine tools: It is used to control
the movement of the machine tool workbench, the feed of the cutting
tool, etc., to achieve precise control of machining dimensions and
shapes and ensure machining accuracy.
Automated production lines, 3D printing, office equipment.
Medical devices and medical imaging equipment: In devices such as
CT and MRI, it is used to control the movement of the scanning bed
and the positioning of the detector to ensure the accuracy and
stability of imaging, as well as the driving of medical devices.
Aerospace and intelligent robots: As the driving element of the
robot joints, it precisely controls the movement of the robot's
arms, legs and other joints, enabling precise movement and attitude
control of the robot, allowing the robot to complete various
complex tasks.
Automobile seat adjustment, automobile window control, and so on.

接线图Wiring Diagram:
Brushless DC motors consist of a motor body and a driver, making
them typical mechatronic products. A brushless motor refers to a
motor without brushes and a commutator (or slip ring), also known
as a commutatorless motor.
- Fully replaces DC motor speed regulation, frequency converter +
frequency conversion motor speed regulation, and asynchronous motor
+ reducer speed regulation.
- Incorporates all advantages of traditional DC motors while
eliminating carbon brushes and slip ring structures.
- Enables low-speed high-power operation, allowing direct drive of
large loads without a reducer.
- Small in size, light in weight, and high in output.
- Excellent torque characteristics, with good medium and low-speed
torque performance, large starting torque, and small starting
current.
- Stepless speed regulation with a wide speed range and strong
overload capacity.
- Soft start/stop and good braking characteristics, eliminating the
need for original mechanical or electromagnetic braking devices.
- High efficiency, with no excitation loss or carbon brush loss in
the motor itself, eliminating multi-stage deceleration losses. The
comprehensive power saving rate can reach 20%–60%, and the purchase
cost can be recovered within one year through power saving alone.
- High reliability, good stability, strong adaptability, and simple
maintenance.
- Resistant to (bumping and vibration), low noise, small vibration,
smooth operation, and long service life.
- No radio interference, no spark generation, particularly suitable
for explosive environments, with explosion-proof types available.
- Optional trapezoidal wave magnetic field motors or sine wave
magnetic field motors as needed.
The main parameters to reference when selecting brushless DC motors
are as follows:
- Maximum Torque: Calculated by summing load torque, moment of inertia, and
friction force, with additional factors such as air gap resistance
influencing it.
- Square Mean Torque: Approximately the continuous output torque required for practical
applications, determined by multiple factors: maximum torque, load
torque, moment of inertia, acceleration, deceleration, and
operation time.
- Speed: The speed required by the application, determined based on the
motor's speed trapezoidal curve. A 10% margin is typically reserved
during calculation.
