A rotary magnetic motor having a rotor configured to magnetically interact with a stator to obtain rotation of the rotor about its axis. The stator has a magnetic structure of a generally involute shape around the axis of rotation. The stator magnetic structure has a plurality of permanent magnets defining a first magnetic face of a first polarity. The rotor has a magnetic structure of a generally circular shape around the axis and inside the stator magnetic structure. The rotor has a plurality of permanent magnets defining a second magnetic face of a second polarity. The magnetic attraction and repulsing of the aligned magnetic faces with a progressively narrowing radial gap, resulting from the involute shape, rotate the rotor inside the stator. A magnetic pulse mechanism discharges a magnetic pulse of the first polarity to provide an additional pull to continue the rotation of the rotor through its full cycle.

A stator core that includes a pair of poles separated by an air gap. Each pole includes a first side adjacent the air gap and a second opposite side remote from the air gap. A pole arc is formed in the first side and an arcuate mounting recess is formed in the second side of each pole. Additionally, an electric machine that includes the stator core.

A modular electromechanical assembly is described. Embodiments of the modular electromechanical assembly can include one or more modules. The one or more modules can be configured to be implemented as a motor, a generator, and combinations thereof. Typically, the one or more modules can be removably coupled together based on a need of a user.

Various embodiments disclosed herein relate to a system and method whereby a haptic feedback mechanism may be integrated into a rotatable gear module such that rotating the module may generate pure mechanical haptic feedback. The gear module may be integrated into a wearable device, such as headphones, such that a set of magnets incorporated within may be aligned and misaligned with a plurality of teeth when the gear module rotates. In response to the rotation, each alignment and misalignment of the set of magnets with the plurality of teeth may generate pure haptic feedback. In embodiments, the gear module may be rotated to increment or decrement a unit of measurement associated with the headphones. Each unit of increment or decrement of change may produce haptic feedback based on the alignment and misalignment of the set of magnets.

Disclosed is an electric generator device (20) including at least one rotor (22), at least one coil (26), and a magnetic or ferromagnetic bridge (24a, 24b). The rotor has an axis of rotation (22c) with magnetic elements (22b) disposed around said axis of rotation. The magnetic elements define pole pairs to create an alternating magnetic field when rotated around the axis of rotation. The coil is away from a direct influence of the alternating magnetic field. The bridge includes a first and second bridge elements joining the rotor to the coil. The bridge elements include teeth (24c) around the magnetic elements so that a voltage within the coil is induced due to the alternating magnetic field within the bridge caused by the rotation of the magnetic elements. The teeth are interdigitated between both bridge halves and their total number correspond to double the number of pole pairs of the magnetic elements.
