Summary:...
Due to its high reliability, wide range of uses, simple maintenance and long service life, geared motors are used for speed adjustment in many equipment. So what are the ways to adjust the speed? Here, I want to tell you that there are two speed control methods, stepwise speed control and stepless speed control, which will be introduced one by one below.
First, let's look at step speed adjustment. Step-by-step speed regulation is a simple and economical speed regulation method, but this speed regulation method is only suitable for 2kw and occasions that do not require much start.
Its speed control has only two gears, so the speed control range is relatively narrow. There are also some
brushless gear motor that can reach the speed adjustment range of the three gears, but only some special cases will use the third gear speed adjustment. When adjusting the speed, a gearbox with gears is required.
Secondly, let us look at stepless speed regulation, which can be divided into two methods: mechanical speed regulation and electrical speed regulation.
Mechanical speed regulation is to add a mechanical stepless speed regulation device where the motor and the gearbox are connected. The advantages of this speed regulation method are relatively simple operation, high speed regulation stability, and can be used in harsh environments, but it also has disadvantages, that is, the speed regulation range is relatively small and frequent maintenance is required.
The electric speed regulation method can realize the rotor resistance speed regulation and cascade speed regulation of asynchronous motors, and the voltage speed regulation and speed regulation of DC motors.
As we all know, the speed adjustment methods of gear reduction motors can be divided into two main types, namely, stepwise speed adjustment and stepless speed adjustment. These two speed regulation methods have their own advantages, disadvantages and scope of application. They can be combined when adjusting the speed. Choose the actual situation.
