Definitions
- the invention is based on an idle turntable according to the preamble of claim 1.
- an idle turntable is already known / the armature of which is tubular and has permanent magnets on the outside.
- a stator with field windings and magnetic guide bodies is arranged around the rotatable armature and is fixedly connected to the housing.
- the construction of this turntable is relatively complex overall.
- the idle turntable according to the invention with the characterizing features of claim 1 has the advantage that it has a part-saving and uncomplicated structure and is easy to assemble.
- the entire electrical part of the servomotor is better protected by the cup-shaped shape of the rotor, for example against contamination from the pneumatic part of the rotary actuator.
- the attachment of encoders is made easier, since the housing parts around the large outer wall of the rotor and around the free shaft end on the rotary valve offer many attachment options.
- Advantageous further developments and improvements of the servomotor specified in claim 1 are possible through the measures listed in claims 2ff.
- a device or an encoder for determining the rotational position of the rotary valve is particularly advantageous. This allows the idle air to be precisely controlled in electronically controlled internal combustion engines.
- the rotary actuator 1 has a servomotor 2, the rotor 9 of which acts on a throttle element 3 which is arranged in a bypass line 4 in a housing 12.
- the bypass line 4 is connected on both sides to an intake pipe 5 with a throttle valve for controlling the idle combustion air of an internal combustion engine.
- the throttle element 3 is seated in an opening 15 of the housing 12 which intersects the bypass line 4 and is designed as a rotary slide valve which more or less closes a control opening 6 in the bypass line 4.
- the arrow indicates the direction of flow in the bypass line 4.
- the servomotor 2 consists of a cup-shaped rotor 9 and a central stator 7 with field windings 8, which stator 7 is arranged within the rotor 9.
- the rotor 9 has a disk-shaped base 16 and a cylindrical jacket-shaped wall 17 extending from the circumference thereof.
- Non-polar permanent magnet segments 10 are preferably arranged on the wall 17.
- the permanent magnet segments 10 are bowl-shaped and cover an angular range of approximately 135 ° each.
- a bore 18 is arranged centrally, which receives a smooth shaft 11.
- the shaft 11 is fixedly connected to the rotor 9 and is mounted with low friction in two bearings 13, 14 held in a housing 12.
- the throttle element 3 controlling the bypass line 4 is fastened to the shaft 11.
- the stator 7 is fastened with its axis 20 to a plate 21 which is arranged on a housing cap 22.
- the housing cap 22 covers the entire servomotor 2 and is connected to the housing 12 with the interposition of a sealing O-ring 23.
- a plug attachment 25 is attached, which has a plurality of plugs 26 arranged one behind the other in the drawing for connecting electrical lines. The ends of the field windings 8 are connected to the plugs 26.
- the idle turntable 1 has an encoder 27 for determining the actual rotational position of the shaft 11.
- the encoder 27 can be arranged in the housing 12 at the end 28 remote from the rotor of the shaft 11 or - as shown in broken lines - opposite the free edge 29 of the wall 17 lie or be arranged at another easily accessible location on the rotor 9 or its shaft 11.
- any location on the housing cap 22 that lies opposite the wall 17 is also suitable.
- the housing cap 22 can be provided with a bore into which an encoder can be inserted from the outside, which sensor scans marks on the wall 17.
- the encoder 27 can be designed as an optical, magnetic or electrical encoder and scans corresponding optical, magnetic, mechanical or electrically effective marks 30 on the rotor 9 or its shaft 11.
- the senor 27 can be designed as an eddy current sensor or as a potentiometer.
- the optical marks can be bar codes, for example.
- the electrical signals from the encoder 27 are transmitted via associated connecting lines 32 (31) e.g. transmitted to the plugs 26 or other connections to the outside. The signals can then be connected to an electronic motor control that continuously monitors and adjusts the rotary position of the throttle device.
