Abstract
A non-output-side end shield (100) for a brushless electric motor (500) is provided, including a centrally arranged bearing seat (110) for accommodating a non-output-side rotor bearing (510) for a rotor shaft (560) of the brushless electric motor (500), the non-output-side end shield (100) including a sensor receptacle (150), which is used as a carrier for a sensor circuit board (550) for detecting the rotational position of the rotor shaft (560), the non-output-side end shield (100) and the sensor receptacle (150) being formed together as a one-part component.
Claims20
A non-output-side end shield for a brushless electric motor, the non-output side shield comprising:
- a centrally arranged bearing seat for accommodating a non-output-side rotor bearing for a rotor shaft of the brushless electric motor;
- a sensor receptacle used as a carrier for a sensor circuit board for detecting a rotational position of the rotor shaft, the non-output-side end shield and the sensor receptacle being formed as a one-part component;
- and
- three slide-in elements, spaced an equal distance apart, and each of the three slide-in openings designed to be accommodated, at least in sections, in a particular one of three slide-in openings belonging to a stator laminated core of the electric motor.
A brushless electric motor comprising:
- a rotor shaft;
- a stator laminated core;
- an output-side end shield having an output-side bearing;
- a non-output-side rotor bearing for the rotor shaft;
- a non-output-side end shield, the non-output side shield including a centrally arranged bearing seat for accommodating the non-output-side rotor bearing;
- and
- a sensor receptacle used as a carrier for a sensor circuit board for detecting a rotational position of the rotor shaft, the non-output-side end shield and the sensor receptacle being formed as a one-part component;
- the output-side rotor bearing being designed as a movable roller bearing.
