High Torque Brushless Motor
Bringsmart manufactures high torque brushless motor, including the following models 2418 2430 2838 3525 3650 4260 motors, which can also be integrated with planetary gearboxes, spur gearboxes, diameters ranging from 16mm 25mm 36mm 37mm 42mm 45mm 4632 5840 to 5882. We insist on using high-quality motor parts and implementing ISO9001 management system, so that our high torque bldc motor can withstand a maximum torque of 40N.M, and can be applied to equipments where high torque is required.
Brushed DC motors have advantages such as high efficiency, miniaturization, electric drive, and low manufacturing cost. However, they also have disadvantages such as noise due to brush friction, spark generation and electrical noise, and shortened life due to brush wear. The emergence of brushless DC motors solves these problems.
Brushed DC motors use brushes and commutators for current switching, while brushless DC motors use sensors and electronic circuits for current switching.
Brushless DC motors have characteristics such as energy saving, long life, low noise, small size, and light weight. They are widely used in continuously operating equipment such as washing machines, air conditioners, and other consumer electronics.

Why is a brushless motor better
High power density: high torque brushless motor structure is more compact, under the same volume, it can brush out a higher number of revolutions and torque, it can output the maximum torque when starting, and there is no mechanical commutator limitation, it has a smaller rotor inertia when running, it can respond to the change of control signals quickly to realize fast starting, stopping and speed change, and it performs well in the application scenarios that require frequent starting, stopping and fast speed change, such as robot joint drive, power tools, etc.
High control precision: small brushless motor speed and steering are precisely controlled by the electronic governor, which can realize the precise adjustment of the motor speed and meet the high-precision requirements for speed regulation in different application scenarios, such as in the transmission system of automated production lines, the motor speed can be precisely controlled according to the requirements of the production process, so as to ensure the stability of the product quality. Combined with suitable position sensors and control systems, brushless motors can realize precise position control, which is widely used in CNC machine tools, semiconductor manufacturing equipment and other equipment that require precise position positioning, helping to improve the processing accuracy and production efficiency of the equipment.
Low noise and electromagnetic interference EMI: small brushless motor adopts electronic commutator, there is no electric spark and friction generated by brushes and commutator, and the magnetic field distribution is more uniform, torque fluctuation is small, the operation is quieter, and the EMI is smaller, which is very suitable for precision instruments or environments that require low decibel.
Longer service life: bldc motor do not have the wear and tear of brushes as brushed motors, which not only saves the cost of regular maintenance of brushes and commutator, but also has a longer service life, which can reach thousands to tens of thousands of hours. The use of brushless motors improves the overall stability of the customer's equipment and projects.
High Efficiency, Energy Saving: brushed motor adopts mechanical commutator, high torque brushless motor adopts electronic commutator, reduce friction loss, energy conversion efficiency can reach 85-90% above, brush motor only 70-80%. Less heat generation, more energy saving.
