The invention relates to a guiding element for use in an electric motor, an electric motor, and a method of installing a rotatable element in an electric motor. The guiding element comprises a guide for a rotatable element of the electric motor. The guide is adapted to radially guide the rotatable element relative to a rotary axis. The guiding element also comprises a centering device adapted to align and/or fix a sensor holding device in the electric motor relative to the guiding element. Moreover, the guiding element comprises a fixing device adapted to fix the guiding element to a housing of the electric motor.

Guiding element for an electric motor

A rotor for an electric motor, comprising a rotor magnet and a bearing for the rotatable support on a fixed axle, the bearing comprising first and second bearing half-shells, wherein at least the first bearing half-shell is moveably arranged within the rotor body with respect to the second bearing half-shell, and wherein the first bearing half-shell is supported against the rotor body by a resilient element tangentially arranged with respect to the axle. The resilient element, at both its side surfaces facing in an axial direction of the axle, has at least one respective first protrusion extending in the axial direction, and the first bearing half-shell, on a side facing away from its bearing surface, includes at least two axially spaced second protrusions each extending in a radial direction and cooperating with the first protrusions for aligning the resilient element.

Rotor with a bearing

A stator for an electrical machine with a stator body () and a ground contact () which is electrically connected to the stator body, wherein the stator body is arranged in a motor housing (), which is formed from plastic material. In order to have a compact stator that is easy to install and at the same time has a reliable contact to a ground contact, it is provided that the motor housing has a stator holder (), which receives the stator body in the operating position, and is located on the inner surface of at least one of its housing parts, and to arrange and fix the ground contact at the inner circumference of the stator holder, facing the stator body, so that the stator body can be electronically contacted by the ground contact.

Stator with ground contact

A drive unit for an actuator having an electric motor, wherein the drive unit comprises a gear train having at least a first gear stage and a last gear stage, wherein the gear train realizes a transmission ratio of greater than one from the electric motor to an output wheel, wherein each gear stage is formed by a gear drive and wherein in the last gear stage, one gear wheel or alternatively two gear wheels connected in parallel are provided that each mesh with an upstream gear wheel of the gear train and with the output wheel, so as to transmit the torque acting on the last gear stage to this stage via the one gear wheel or alternatively distributed over the two gear wheels connected in parallel, wherein the drive unit is accommodated in a housing of the actuator that has at least a first and a second bearing support for the gear wheels of the last gear stage, and to form this last gear stage, the two bearing supports are fitted with the one gear wheel or alternatively with the two gear wheels connected in parallel.

Drive unit for actuator drive including an electric motor and actuator drive

A housing for an actuator for receiving an electric motor and further functional units of the actuator, wherein a can is integrally molded to an inner face of the housing that is designed to receive the electric motor and wherein means of fastening are integrally molded to the can that are designed to position and fix the electric motor accommodated in the can.

Housing for an actuator for receiving an electric motor and an assembly

A directly coupled linear drive having a drive unit and a sliding element that are disposed in a frame, the sliding element, actuated by the drive unit, being capable of effecting a movement in a direction of translation with respect to the frame and having a blocking device for blocking the sliding element in the frame in the event of a shock load to the sliding element, the blocking device having a body coupled to the sliding element that absorbs the shock load and is disposed such that the shock load of the body counteracts the shock load of the sliding element.

Linear drive having shock compensation

The invention relates to an electromechanical motor having a stator that has a drive unit and a frame component in which the drive unit is held, and a sliding element that is constructed such that, actuated by the drive unit, it performs a movement with respect to the stator in a direction of translation, wherein the drive unit has at least one electromechanical drive element that extends in the direction of translation and a power transmission element that is constructed so as to transmit a movement of the drive element to the sliding element. The sliding element has a supporting component and a drive rail, the drive rail extending in the direction of translation and interacting with the power transmission element and the drive rail being held at both its end faces in the supporting component, and between the supporting component and the frame component of the stator, there is a bearing for supporting the sliding element in the frame component.

Electromechanical motor

The invention relates to a device for the insulation of the stator slots of an electric machine that has a stator having a plurality of stator poles and stator slots located between the stator poles, comprising an insulating body that has moldings adapted to the shape of the stator slots and can be slid onto the stator in an axial direction, and a cover piece that can be connected to an end face of the insulating body, in order after the windings have been applied to the insulating body, to carry the windings () at the end face of the stator and to cover them.
