Brushless dc gear motor, speed reducer adopts planet gear structure, steady transmission, large loading, 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? 1, brushless dc gear motor, compact structure, small size, beautiful shape, ability to withstand overload. 2, transmission ratio, fine classification, selection range, speed spectrum, wide range I = 2 -28800. 3, brushless dc gear motor, low energy consumption, superior performance, 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, new type of sealing device for the brushless dc gear motor, good protection performance, strong adaptability to the environment, can be in harsh environments, such as corrosion, wet work continuously. 6, alternative dc motor speed regulation, frequency converter, asynchronous motor + reducer + frequency conversion motor speed control. 7, possesses the advantages of traditional dc motor, 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 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.
