DC Motor Types
Brushed DC Motor
Brushed DC motors work by having the coil rotate inside the surrounding magnets. The rotation of the coil causes the contact between commutator and brush to alternate, therefore switching the current flow through the coil. As a result, the brushed DC motor can operate.
Brushless DC Motor
A Brushless DC Motor (BLDC) is an electric motor powered by a direct current voltage supply and commutated electronically instead of by brushes like in conventional DC motors. BLDC motors are more popular than the conventional DC motors nowadays, but the development of these type of motors has only been possible since the 1960s when semiconductor electronics were developed.
Gearbox Types
Spur Gearbox
Spur gears are used in mechanical applications to increase or decrease the speed of a device or multiply torque by transmitting motion and power from one shaft to another through a series of mated gears.Spur gears are more efficient compared to helical gears with the same size. They are quite reliable and offer constant velocity. Spur gears are also considered a member of positive transmission because they don't have any slippage
Planetary Gearbox
A planetary gearbox is a gearbox with the input shaft and the output shaft aligned. A planetary gearbox is used to transfer the largest torque in the most compact form (known as torque density).Planetary gear systems are able to produce a lot of torque because the load is shared among multiple planet gears. This arrangement also creates more contact surfaces and a larger contact area between the gears than a traditional parallel axis gear system.
Worm Gearbox
Worm gears operate by the friction created by turning lubricated gears. The friction is then converted into heat. By producing a low speed and high-speed torque level, worm gears are utilised as speed reducers, which implies that they are ideal for several applications. In theory, a worm gear is self-locking when the static friction angle is larger than the helix angle of the worm. The static friction angle is described as the angle where the load above will start to move.

BLDC Planetary gear motor: Types, Features, and Functions
A BLDC planetary gear motor comprises a brushless DC motor and a planetary gearbox to its advantage. It is a compact and efficient power transmission solution widely used in various industries and applications.
The BLDC planetary DC gear motor is an electric motor that operates using electronic commutation, thereby reducing the need for regular maintenance and wear, resulting in a longer lifespan and improved reliability.
Using electronic commutation, Brushless DC gear motors don’t need brushes and commutators. Instead of brushes, BLDC motors incorporate a controller that precisely controls the switching of current to the motor windings. This electronic commutation reduces friction and wear, allowing for smoother operation and increased efficiency.
Furthermore, the brushless design offers other benefits contributing to the extended lifespan. With fewer mechanical components, fewer points of failure result in enhanced durability. Additionally, the electronic commutation system enables better control over the motor, reducing stress on the gears and ensuring smoother and more efficient power transmission.
To recap, BLDC planetary gear motors outperform their brushed counterparts in terms of lifespan due to the utilization of brushless DC motors. Eliminating brushes and adopting electronic commutation significantly reduce wear, increase efficiency, and improve overall reliability. This makes brushless planetary gear motors a preferred choice in applications where longevity and consistent performance are essential.
Why the BLDC planetary gear motor's noise is very low?
The low noise in this unique gear system is based on the brushless motor, the planetary gear system it uses, and proper lubrication. Let’s start with the first, which is the brushless motor. This characteristic eradicates friction which is the common noise source in brushed motors. As a result, there are no brushes to wear out or generate audible vibrations during operation.
Additionally, the planetary gear system employed in these motors contributes to their low noise output. The gear arrangement distributes the torque across multiple gears, reducing the load on each gear tooth. This helps to minimize gear rattling and vibrations that could otherwise generate noise.
Proper lubrication is essential for minimizing the noise generated by a DC planetary gear motor. Applying the appropriate lubricant to the gears and bearings can reduce friction and wear, resulting in smoother and quieter operations. The lubrication forms a protective film between the gear teeth, preventing metal-to-metal contact and dampening vibrations. It also helps to dissipate heat, maintaining optimal operating conditions. Regular lubrication maintenance ensures the motor operates quietly and efficiently, prolonging its lifespan and enhancing overall performance. Choosing a high-quality lubricant for gear applications can significantly reduce noise and improve the overall user experience.
Furthermore, brushless motors typically utilize electronic commutation, which is more precise and efficient than brushed motors’ mechanical commutation. This electronic commutation results in smoother operation and reduced vibration, further contributing to the low noise level of BLDC planetary gear motors.
The combination of brushless technology, planetary gear design, and electronic commutation enables these motors to operate with minimal noise, making them suitable for applications where quiet operation is desired or required.
How BLDC Planetary Gear Motor built-in driver works?
A BLDC planetary gear motor is a compact and efficient motor whose torque output is high and offers smooth operation and precise control. The motor is driven by a built-in driver, which plays a crucial role in its operation.
The built-in driver of a BLDC planetary gear motor controls the motor’s speed, direction, and other parameters. It receives power through the power supply cables consisting of positive (+) and negative (-) terminals. These cables provide the necessary voltage and current for the motor’s operation.
The direction control cables, often called CW (clockwise) and CCW (counterclockwise), enable the driver to change the motor’s rotational direction while the PWM control cable allows the driver to modulate the motor’s speed by adjusting the pulse width modulation signal. By controlling the current flow through these cables, the driver can determine the desired direction of rotation and regulate the motor’s speed.
The signal feedback cable transmits information about the motor’s rotational speed, position, and other feedback data. This feedback helps the driver adjust and optimize the motor’s performance.
Lastly, the brake control cable is responsible for activating the brake mechanism in the motor. When the brake control signal is applied, the motor stops quickly and securely.
To sum it up, the built-in driver of a BLDC planetary gear motor integrates these cables to provide precise control and efficient operation, making it a versatile choice for various applications.

How does BLDC Planetary Gear Motor works?
- BLDC Motor Constructionfor brushless planetary gear motor:
The brushless DC motor consists of a rotor and a stator. The rotor comprises permanent magnets, while the stator consists of windings. The windings are energized in a sequence to create a rotating magnetic field.
- Working of BLDC Motorfor BLDC planetary gear motor:
The BLDC motor converts electrical energy into mechanical energy. The electronic controller switches DC currents to the motor windings, producing magnetic fields that rotate in space. The rotor follows these rotating magnetic fields.
- Planetary Gearbox Constructionfor brushless planetary gear motor:
For the bldc planetary gear motor, planetary gearbox consists of three main components: a central or “sun” gear, multiple “planet” gears, and a “ring” gear. The sun gear is at the center, with planet gears orbiting around it, similar to our solar system. All these components are enclosed within the ring gear.
- Working of Planetary Gearboxfor brushless planetary gear motor:
When the sun gear (driven by the motor) rotates, it causes the planet gears to rotate as they mesh with the sun gear. The planet gears also mesh with the ring gear on the inner wall of the planetary gearhead housing. Depending on the configuration, any of these three main components – the sun gear, the planet gears, or the ring gear – can serve as the input (receiving power from an external source), output (delivering power to perform work), or can be held stationary (held fixed or immobile during operation).
- Output Shaft:
Finally, for brushless dc planetary gear motor, the mechanical energy is transmitted from the brushless DC motor to planetary gearbox, to the shaft output, controlling speed and direction.
