Abstract
A stator for a linear motor is described. The stator has a stator member with a coil arrangement, a connecting member with external terminals, a sensor arrangement having at least one Hall sensor, and terminals for the sensor arrangement, as well as a holding member. The holding member is subdivided into a connecting member insertion portion and a stator member insertion portion and has holding devices for disposing the stator member and the connecting member stationarily, releasably and in an accurate position with regard to each other.
Claims17
A linear motor stator comprising:
- a stator member having a coil arrangement;
- a connecting member having at least one external terminal;
- a sensor arrangement comprising at least one Hall sensor, and terminals for the sensor arrangement;
- and
- a holding member comprising:
- a connecting member insertion portion configured to receive the connecting member;
- a stator member insertion portion configured to receive the stator member;
- a plurality of holding devices configured to releasably retain the stator member and the connecting member in an accurate position with regard to each other;
- and
- at least two attachment portions configured to affix the stator to a carrying profile of the holding member,
- wherein the attachment portions extend in a direction leading away from a rotor, the rotor corresponding to the stator member, each attachment portion having a respective fixing device.
A linear motor stator, comprising:
- a stator member having a coil arrangement;
- a connecting member having at least one external terminal;
- a sensor arrangement comprising at least one Hall sensor, and terminals for the sensor arrangement;
- and
- a holding member comprising:
- a connecting member insertion portion configured to receive the connecting member;
- a stator member insertion portion configured to receive the stator member;
- a plurality of holding devices configured to releasably retain the stator member and the connecting member in an accurate position with regard to each other;
- and
- a separation wall configured to provide the subdivision of the holding member, the separation wall disposed at the holding member between the connecting member and the stator member.
The linear motor stator according 4, wherein the separation wall comprises a horizontally and centrally disposed section, which extends in a direction away from a rotor,
- wherein the holding member comprises at least one sidewall section at least in an area of the separation wall disposed in the direction away from the rotor and extends essentially perpendicularly with regard to the separation wall,
- whereby a reception space is formed between the section of the separation wall and the at least one sidewall section.
A linear motor stator comprising:
- a stator member having a coil arrangement;
- a connecting member having at least one external terminal;
- a sensor arrangement comprising at least one Hall sensor, and terminals for the sensor arrangement;
- and
- a holding member comprising:
- a connecting member insertion portion configured to receive the connecting member;
- a stator member insertion portion configured to receive the stator member;
- and
- a plurality of holding devices configured to releasably retain the stator member and the connecting member in an accurate position with regard to each other,
- wherein the holding devices comprise holding projections between which the connecting member is clipped.
