Brushless dc gear motor reducer adopts planet gear structure of the controller, have passed smoothly, large bearing capacity, small volume of large torque, low energy consumption, is one of the important development direction in the future. What are the characteristics of the brushless dc gear motor controller? 1, brushless dc gear motor, controller structure is compact, small volume, aesthetically pleasing, withstand overload ability. 2, transmission ratio, fine classification, selection range, speed spectrum, wide range I = 2 -28800. 3, low energy consumption, brushless dc gear motor controller performance is superior, the reducer efficiency is as high as ninety-six percent, small vibration, low noise. Is 4, strong commonality, use convenient maintenance, low maintenance costs, especially in the production line, just standby within several transmission parts can guarantee the normal production of the whole line maintenance. 5, brushless dc gear motor controller using the new sealing device, protection performance is good, strong adaptability to the environment, can be in harsh environments, such as corrosion, wet work continuously. 6, alternative speed dc motor controller, inverter + variable frequency speed regulating motor controller, asynchronous motor + reducer speed controller. 7, possesses the advantages of traditional dc motor controller, and cancelled the carbon brush and slip ring structure at the same time. 8, can run for high power at low speed, can save reducer drive big load directly. 9, high reliability, good stability and strong adaptability, simple maintenance and maintenance. 10, do not produce sparks, is especially suitable for explosive place, explosion-proof type. Brushless dc gear motor controller in the market, there is no standard, the standard specifications of power to power is usually to customize according to customer's requirements, parameters, specifications and other factors.
