Embodiment Construction

[0011] like figure 1 , figure 2As shown, the planetary gear converter has a set of planetary gear reversing device J, a frequency conversion controller 13 and a circuit change switch K, and the micro-motor 10 in the planetary gear reversing device J is installed on the reversing wheel Z0, The reversing wheel Z0 is well meshed with the sun Z, and the micro-motor 10 is connected to the frequency conversion controller 13 outside the rotor casing, and the frequency conversion controller drives the positive and negative rotation of the sun gear Z, thereby changing the number of channels M of the multi-channel variable stator coil 1 . The planetary gear reversing device J is divided into two different structures: the steering brush type planetary gear reversing device J1 and the fixed brush type planetary gear reversing device J2. The steering brush type planetary gear reversing device J1 consists of a center Sun gear Z, two first planetary gears Z1 and second planetary gears Z2 ...

Abstract

The invention discloses a star wheel transformer, which comprises a planetary gear reversing device, a variable frequency controller and a variable path switch, wherein the planetary gear reversing device is divided into two different structures, namely a steering brush type planetary gear reversing device and a fixed brush type planetary gear reversing device, wherein a micro motor in the planetary gear reversing device is arranged above a reversing wheel; the reversing wheel is in good engagement with a sun gear; the micro motor is connected to the variable frequency controller outside a rotor shell; the forward and reverse rotation of the sun gear is driven, so that the path number M of the multi-path variable stator coils is changed, and thus the structure is greatly simplified and isonly equivalent to a direct current motor commutator, and complex electronic facilities and even an expensive and large-size solid-state relay are not provided; and furthermore, the star wheel transformer is accurate in action, safe, reliable, resistant to vibration and low in cost, and an electric brush does not need to be replaced in the life, so that the power of the motor can be changed in a multiplied mode in a running process easily, and the positive significance is very obvious.

Description

technical field [0001] The invention relates to a converter installed inside a variable power motor, especially a converter with a planetary gear steering device. Background technique [0002] Our company's invention patent application variable power motor (application number 2018108300318) and external rotor variable power motor (application number 2018108528678) disclose variable power motors that can double the power, and are widely used in electric vehicles and other fields. The electric converter used in it is installed outside the motor. For the external rotor variable power motor, if the electric converter is installed outside the casing, more cables must be drawn out from the lead hole of the crankshaft, resulting in a certain Difficulties. Contents of the invention [0003] The purpose of the present invention is to provide a switch that can be installed inside the casing, so that it is not necessary to lead out redundant cables from the lead hole of the cranksha...
