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.

How the Square Geared DC Motor Works?
The square geared DCĀ motor operates by utilizing the principles of mechanical power transmission through a system of gears. Here’s an easy-to-follow breakdown of how a square gear motor generally operates:
1.The square geared DCmotor receives electrical power input from an outside power source, typically in the form of direct current (DC). This electrical energy is transformed inside the motor into mechanical energy.
2. Thesquare geared DC motor’s electric motor transforms electrical energy into rotational motion. A stator with wire windings serves as the motor’s stationary component, along with the rotor, which rotates. An electromagnetic field is produced when an electric current is run through the windings, which causes the rotor to rotate.
3. The gear system receives the rotational motion produced by the motor. A set of gears, usually spur gears or helical gears, are arranged in a square or rectangular pattern by thesquare geared DC The gears mesh together and make contact with one another, transferring rotational force and torque.
4. The gear system transmits the rotational motion of the motor, and the gears work together to either increase or decrease the output speed and torque. The degree of reduction or amplification is determined by the particular gear arrangement and ratios. To balance speed and torque, square gear motors typically offer moderate gear reduction ratios.
5. The output shaft of the square geared motor is connected to the final gear within the gear system. As the gears rotate, the motion is transferred to the output shaft. This shaft extends from the motor housing and delivers the rotational output to the external mechanical system or load.
6. The rotational output from thesquare geared DC motor is utilized to drive or operate the intended load or mechanical system. The load can differ significantly depending on the particular application. It might entail maneuvering machinery, rotating arms, or any other activity requiring precise and controlled rotational motion.
Throughout this process, the square gearedĀ motor ensures efficient power transmission and reliable performance.
