Summary:...
Due to the high reliability, wide use, simple maintenance and long service life of the
brushless gear motor, it is used in many equipment to adjust the speed. There are two ways to adjust the speed. There are two types of speed regulation and stepless speed regulation. introduce.
First of all, let's take a look at the stepped speed regulation. The stepped speed regulation is a simple and economical speed regulation method, but this kind of speed regulation method is only suitable for the occasions of 2kw and does not require much start.
Its speed regulation is only two gears, so the range of speed regulation is relatively narrow. There are also some gear reduction motors that can achieve the speed regulation range of three gears, but only some special occasions will use the third gear speed regulation. When adjusting the speed, a gearbox with gears is required.
Secondly, let's take a look at stepless speed regulation, which can be divided into mechanical and electrical speed regulation methods.
Among them, mechanical speed regulation is to add a mechanical stepless speed regulation device where the motor and the gear box are connected. The advantage of this speed regulation method is that the operation is relatively simple, the speed regulation stability is high, and it can be used in harsh environments, but there are also 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 the asynchronous motor, as well as the voltage regulation and speed regulation of the DC motor.
It can be known that the speed regulation methods of gear reducer motors can be divided into two main types, namely step-wise speed regulation and stepless speed regulation. Each of these two speed-regulation methods has its own advantages and disadvantages and scope of application, and can be combined when adjusting speed. Choose the actual situation.
