Definitions

  • the invention relates to a device for switching the speed of an electric motor with a plug that can be connected in different positions to the plug receptacle of the electric motor and, depending on its insertion position, generates different circuits of the motor developments and thus different motor speed levels.
  • the object of the invention is to provide a motor series, in particular for pumps, in which a voltage and speed changeover is made possible by a single plug, the plug providing the necessary connections for this purpose with only one plug side.
  • the teaching according to the invention can be expanded as desired, so that more than one further plug position (D) with associated winding circuits can be present outside the steps of the first or second voltage level.
  • a structurally particularly simple and safe solution is achieved when the connector position (A, D) located outside the voltage level is blocked by a mechanical lock in or on the connector receptacle and / or on the connector.
  • the permissible connector positions (A-C, B-D) can be reached by means of positive guides. It is particularly advantageous here if the mechanical lock can be switched on and off by an adjusting tool.
  • all contacts of the plug receptacle are in the same plane, or that all contacts of the plug are in the same plane.
  • all contacts of the plug and / or the plug receptacle are each attached to the same board.
  • the first three winding circuits A-C are used for a first voltage level e.g. 230 volts and the last three winding circuits B-D for a second voltage level e.g. 400 volts used.
  • the winding circuits AC form the first, second and third speed stage, with the winding circuit A generating the first speed stage with maximum speed, the second winding circuit B with the second speed stage with medium speed and the winding circuit C with the third speed stage with the lowest speed .
  • the three winding circuits are generated by a plug which can be inserted into four different positions in the plug receptacle, the winding circuit A being generated in the first plug position, the winding circuit B etc. being generated in the second plug-in position.
  • the plug and plug receptacle or socket are designed so that when the first voltage level is used, the plug position D and thus the winding circuit D are blocked, so that only the positions AC can be reached.
  • the plug and / or the socket is changed mechanically in such a way that the plug can only reach positions BD, but not position A, so that only the winding circuits BD through with the connector same page can be generated.
  • the first and thus maximum speed level is generated by the connector position A and the circuit A
  • the first connector position A is now blocked at the second voltage level and the first speed level with the maximum speed is at the connector position B with the winding circuit B. generated.
  • the winding circuit D can now be reached as the third stage with a minimal speed, so that at the second voltage level the winding circuit D has the same effect as the winding circuit C at the first voltage level.
  • the first three AC can be reached by the first three plug circuits within a first voltage level and the last three winding circuits by the three plug positions BD for a second voltage level, this always with the same plug and with its same side is reached.
  • the first stage A of the first voltage level produces approximately the same power or speed as the first stage B of the second voltage level.
  • All contacts of the plug as well as the plug receptacle are on the same level and are attached to the same board.
  • a single further connector position D or A there may also be several, in particular two, positions, so that, for example in the case of a row of AE, the winding circuits AC can be reached at the first voltage level and the winding circuits CE can be reached at the second voltage level.
