Brushless gear motors have gained significant popularity due to their efficiency, reliability, and versatility in various applications, such as robotics, automation, electric vehicles, and more. To ensure the longevity and optimal performance of these motors, proper maintenance is essential. This article will provide a comprehensive guide on how to maintain brushless gear motors effectively.
Brushless DC (BLDC) gear motors have gained immense popularity due to their efficiency, reliability, and precise control in various industrial and consumer applications. Whether you are designing a robotic arm, an automated conveyor system, or an electric vehicle, selecting the appropriate BLDC gear motor is crucial to ensure optimal performance. In this article, we will guide you through the key considerations to help you make an informed decision when choosing a BLDC gear motor.
Brushless motor has an irreplaceable role in the industrial field. It is precisely because of the outstanding role of brushless DC motor that it also needs long-term use. After the brushless motor is overloaded, the current will be too large, which will aggravate the motor fever, burn out the motor for a long time, and even cause a fire. So we should do a good job of maintenance, so as to make it work. So what should we do? In this article, we will introduce 4 tips about BLDC motor maintenance.
Both motor KV and the number of poles are related to the speed/RPM of the motor. We know that as the RPM increases, the KV value also increases. Alternatively, a higher number of poles corresponds to a motor running at a lower RPM. Therefore, the relationship between the number of motor poles and the KV value is inversely proportional. This makes sense when we actually consider it.
As a power source for all kinds of machinery, motors are used in a wide range of applications, from heavy industry to small toys. In daily use, it is necessary to adjust the speed of the forward and reverse rotation of the motor. The following describes the use of potentiometers to control the speed of brushless DC motors.
The stator of a brushless motor is the part that generates the rotating magnetic field and can support the rotor to rotate. It mainly consists of a silicon steel sheet, enameled wire, bearing, bracket, etc.; the rotor can support rotor rotation under the action of the stator rotating magnetic field, and the parts mainly consist of the rotor shaft, magnet, bracket, etc. In addition, the number of pole pairs formed by the stator and rotor will also affect the speed and torque of the motor.
The power supply of the DC brushless motor is connected to the brushless motor through the controller so that the DC brushless motor runs in one direction. Looking at the direction of the motor shaft extension, the motor shaft rotates clockwise is called forward rotation, and counterclockwise rotation is called reverse rotation. The following is explain how to wire a controller to reverse a BLDC motor.
The wiring principle of the general brushless DC motor is basically similar. Here we take a 24V brushless motor as an example to show you how to connect the motor to the controller and make the motor turn.
To test 24V BLDC motor requires a controller, 24V DC power supply start switch, a push button switch & a toggle switch, including power wires and hall wires, as well as a resistive accelerator pedal. All of these constitute the basic parts to operate a BLDC motor.
A brushless motor is mainly used to generate driving torque as a power source for appliances or various machinery, and its main function is to use mechanical energy to convert it into electrical energy. Under the action of torque of mechanical equipment installed with a brushless motor, the object will change in position or angle, etc. Therefore, it can be calculated according to the formula of the definition of Aki torque. That is, torque (T) = power (P) * 9.55 / number of revolutions (N), or mutual conversion factor can also look like this: T * number of revolutions / 9.55 = power
The brushless DC motor is developed on the basis of the brushed DC motor. It has step-less speed regulation, a wide speed regulation range, strong overload capacity, good linearity, long life, small size, lightweight and large output. Brushless motors are widely used in industrial equipment, instrumentation, household appliances, robots, medical equipment, etc. Since the brushless motor does not have brushes for automatic commutation, it needs to use an electronic commutator for commutation, which can be achieved by purchasing a matching brushless DC motor controller.
