Because the motor shaft rotational speed of tubular motor is too fast, for the convenience of use will generally set up the reduction gear on tubular motor to make the rotational speed of output shaft satisfy normal use needs. The existing direct current tubular motor is generally a common rare earth or ferrite motor, and has the structural characteristics that a rotor core and magnetic shoes are attached to a shell and the like. Existing tubular rare earth or ferrite motors suffer from a number of disadvantages, for example: 1. the rotor core is provided, and the mass of the rotor core is large, so that the rotor has low response speed, high energy consumption and large vibration when being started and stopped, the damage to parts is serious, and the service life of the whole machine is limited; secondly, the rotor core can generate eddy current in the magnetic field, which can cause the motor to generate heat, and has high energy consumption and low efficiency. 2. The magnetic shoe (permanent magnet) is fixed on the shell, the magnetic shoe (permanent magnet) must have certain thickness, and under the condition that the motor outer diameter is certain, the outer diameter size of the motor rotor can be greatly limited, so that the output torque of the motor is greatly limited. In addition, the reduction ratio of the speed reducer of the existing tubular motor cannot meet the requirement, the structure is not compact enough, the stability of the transmission process is poor, and great inconvenience is caused when the existing tubular motor is used by the problems.
In order to solve the defects of the prior art, people have long searched for and put forward various solutions. For example, the chinese patent document discloses a tubular motor planetary reducer [200720184522.7], including a sun gear, an internal-tooth end cap, an internal-tooth sleeve, and an internal-tooth sleeve holder, characterized by having therein: the primary support main body is provided with three support pins, a primary planetary gear is arranged on each support pin, and a gear is arranged at the lower end of each support pin; the secondary support comprises a secondary support main body, wherein three support pins are arranged on the secondary support main body, secondary planet gears are arranged on the support pins, and gears are arranged at the lower ends of the support pins; the three-stage support comprises a three-stage support main body, wherein three support pins are arranged on the three-stage support main body, three-stage planetary gears are arranged on the support pins, and an output shaft is arranged at the lower end of the support pins. The scheme solves the problem that the reduction ratio of the speed reducer of the existing tubular motor cannot meet the requirement to a certain extent, but the scheme still has a plurality of defects of a common rare earth or ferrite motor, and meanwhile, the scheme still has other defects, such as poor transmission stability and the like.
