摘要： A magnet yoke of a linear motor includes a plurality of recesses set in equidistance in a side surface of the magnet yoke and defining a plurality of peaks and valleys arranged alternately and a plurality of permanent magnets aligned abreast in equidistance in an opposite side surface of the magnet yoke so that an interval is defined between two adjacent permanent magnets and has a center aligned with a center of a corresponding peak and valley. Two adjacent permanent magnets form a magnet unit for generating a magnetic flux distribution. An empty section formed in each of the valleys is twice as wide as an interval between two adjacent permanent magnets, and is located in a middle of the two permanent magnets so as to make a moderate magnetic flux distribution.

摘要： A linear motor mover with heat dissipation unit includes: a base seat; a mover having several coils sequentially upright arranged with first ends of the coils disposed in the base seat; a heat dissipation unit having a hollow and substantially slat-shaped cooling section, one face of the cooling section being immediately adjacent to second ends of the coils opposite to the base seat, whereby the heat generated by the coils during operation of the mover can be conducted from the coils to the cooling section, the cooling section containing a cooling fluid therein, the cooling fluid flowing within an interior of the cooling section to carry away the heat absorbed by the cooling section; and an insulation section disposed between the heat dissipation unit and the coils. With the heat dissipation unit, the linear motor has better heat dissipation efficiency and driving efficiency and is assembled at lower cost.

摘要： A shielding structure disposed between a rotary motor and a resolver for resolving angular position thereof. The shielding structure includes a first shielding body made of a material with a permeability more than 4000. The first shielding body is sandwiched between the resolver and the rotary motor for shielding the resolver from the rotary motor. The first shielding body provides a path of low magnetic resistance to change the direction of magnetic flux and lower the electromagnetic interference of the magnetic field with the operation of the resolver. Accordingly, the resolver can more stably output resolution signals at higher precision.
