Speed regulation method of the gear motor

Speed regulation method of the gear motor

The gear motor is a fixed speed gear motor, once the speed ratio is selected and the motor is selected, the  final output speed is fixed. However, in actual use there are many occasions where speed is required to change, such as the spindle speed of lathe, the speed of stirring shaft of various stirrers, the conveyor speed when conveying different items, etc. How to adjust the speed is a topic of great concern to engineers and technicians. The following is a brief description of the various speed control methods used in engineering.

1. Variable-pole speed regulation is the simplest and most economical speed regulation method. But only limited to small and medium capacity (2kw or less) and the occasion of the number of starts. Usually only two speed, can achieve the speed ratio is also small (l:2 a 6), the limit to do three; in some specific industries, such as lathes, etc., often with a gear box with a row of gears for speed regulation. Although there are children gear speed, but the speed range is not large.

2. Stepless speed control can be divided into mechanical and electrical type. The former common method is in the motor and gearbox linkage inserted into the mechanical stepless speed control device (mainly belt disc type, friction disc type). The advantage is that the speed is smooth, uncomplicated structure, suitable for harsh environments; disadvantage is that the speed range is small (generally within 1:lO) basin belt and friction disc is a wear parts, need to be regularly maintained and replaced. The latter is a series of asynchronous motor speed regulation, rotor resistance speed regulation or DC motor for voltage regulation, etc.
