A rotary electric machine includes a stator; and a rotor including an iron core, which has a tubular connecting portion surrounding a shaft and 10 magnetic pole portions integrally formed with the connecting portion corresponding to a pole number, and a plurality of permanent magnets arranged between the magnetic pole portions. The iron core includes axially-penetrated magnet accommodating air gaps formed between the magnetic pole portions at the radial outer side of the connecting portion, and the permanent magnets are installed in the respective magnet accommodating air gaps such that a radial outer surface of each of the permanent magnets makes close contact with an inner surface of each of the magnet accommodating air gaps and such that a gap exists between a radial inner surface of each of the permanent magnets and the connecting portion.

Rotary electric machine with tapered permanent magnet

The disclosure discloses a rotating electrical machine that is integrally formed with a reduction device having an input shaft to which a roller gear cam is provided and an output shaft to which cam followers configured to sequentially engage with the roller gear cam is provided on an outer periphery, extending along a direction orthogonal to the input shaft, and is configured to employ one of a field system or an armature as a rotator and the other of the field system or the armature as a stator, including a rotating shaft that is fixed to the rotator and integrally formed as a single shaft with the input shaft of the reduction device.

Rotating apparatus having rotating electrical machine and reduction device with common rotating shaft

This disclosure discloses a rotating electrical machine that is integrally formed with a reduction device having an input shaft and an output shaft and employs one of a field system and an armature as a rotor and the other of the field system and the armature as a stator, including a rotating shaft to which the rotor is fixed and that is coaxially connected to the input shaft of the reduction device, and a bearing support member configured to support bearings that rotatably support the input shaft of the reduction device, wherein the stator is provided to the bearing support member.

Rotating electrical machine and rotating apparatus

A motor includes: a almost annular stator, a rotor arranged inside the annular ring of the stator for rotating about a central axis, a sensor for detecting the rotation of the rotor, and a sensor board for implementing the sensor. The sensor and the sensor board are arranged outside the stator in the direction along the central axis. The sensor is a reflection type light projecting/receiving sensor.

Rotating electrical machine

A stator includes: a stator core having an almost annular outer core and an inner core arranged inside the outer core; and a bobbin having a cylindrical body part around which a winding wire is wound and a flange part that is formed so as to rise up from the cylindrical body part, with a plurality of bent parts and an edge part.

Stator and rotating electrical machine

In a coolant-cooled linear motor includes an armature including armature windings and a cooling jacket arranged to surround the armature windings, the cooling jacket unit includes four cooling jackets defining four side faces parallel to the extension direction of the armature and two end blocks defining two opposite end faces in the extension direction of the armature, the cooling jackets and the end blocks being connected to one another in a box shape. Each of the cooling jackets has an internal space to be supplied with a coolant; and a field magnet unit includes a yoke made of a ferromagnetic material and permanent magnets arranged in the yoke, one of the armature and the field magnet unit making relative movement with respect to the other.
