What robot motor controller? Robot brushless dc motor controller
what robot motor controller? Robot robot brushless dc motor controller in the concept of a lot of people's appearance is similar to human, through the computer instructions in all kinds of action. Is part of the simulation robot is modeled on the human to create, but in fact use most robots is in industrial production, and the appearance of this kind of robot is not similar to the human, is likely to be a side shell plus a few of mechanical arm. The rapid development of robots, ushered in a new era of industrial production. Robot to perform specific tasks planned in advance, such as assembly line work, surgical aid delivery, warehouse/retrieval, even the mines and other dangerous tasks. Now robots can not only deal with high repetitive work, also can accomplish need flexibility on the direction and the action of complex function. With the progress of technology, speed and flexibility of ascension, the cost is lower, the robot will be widely adopted gradually. Under artificial cost advantage also let us see the robot industry's huge development potential. In addition, machine vision, computing power, and the progress of the network will also promote the popularity of robot applications. The high performance of the robot to realize benefit from the promotion of the following several aspects: 1. Complex sensor; 2. Real-time decision-making and action of computing power and algorithm; 3. Fast and accurate mechanical power to realize the motor controller of complex tasks; When choose the specific types of motor controller and model, to consider the three main factors: 1. The minimum and maximum speed motor controller ( And acceleration) 。 2. Motor controller can provide the maximum torque, and the relationship between the torque and speed curve. 3. Motor controller ( No sensors and closed loop control) The accuracy and repeatability. When choosing motor controller, of course, there are many other such as size, weight and cost, and other important factors to consider. For almost all small to medium-sized robots the size of the drive, such as the choice of drive motor controller is usually brush dc motor controller, brushless dc motor controller, stepper motor controller and the servo motor controller, etc. A brushless dc motor controller is the original dc motor controller technology, the most simple structure, is also the lowest cost. Due to the contact between the brush and the rotor, the rotation of the rotor motor controller will switch ( The reversing) The magnetic field around the rotor winding. The speed of the motor controller is a function of applied voltage, so the driver request is not high, but it is difficult to manage torque. Because the brush wear, need to clean up, maintenance, and may become the electronic noise ( The electromagnetic interference) Factors such as work and reliability problems. As a result of the existence of these problems, in most cases, the most in the design of brushless dc motor controller has become a robot is not an attractive option. Brushless dc motor controller is a new type of controller, the advantage of the brushless dc motor controller is embodied in the development of two aspects: the first is to use the strong permanent magnets, small size, low cost; The second is to use small size high efficiency electronic switch to switch to winding current. 'Electronic commutation' replaced with mechanical brush motor controller in always control the switch of the magnetic field, on the fixed switch coil with a rotation around the core of the interaction between the magnets to replace the mechanical commutator brush motor controller, it is using the interaction between the magnetic and electric fields. In addition, relative to the motor controller, the motor controller controller can better control the controller performance. Compared with a brush motor controller, brushless dc motor controller, while the need for more complex control circuit of but can show a better performance. Brushless dc motor controller usually needs a position feedback sensors, such as hall effect sensors, optical encoder, or counter electromotive force detection device. With the progress of technology, including by improving motor control and sensing will create new opportunities brought about by the executed precisely, the prospect of the robot is very considerable. In the field of sensing, control, and motor controller is the key to revolution will continue to affect change of robot technology.
