摘要： The present invention provides a ring varistor for use in DC micromotor including a ring varistor substrate having nonlinear volt-ampere characteristics and at least three independent electrodes evenly sintered on an end face of the ring varistor substrate. The electrode gap between two adjacent electrodes consists of two straight parallel edges of the two adjacent electrodes, and an inner and an outer concentric arc on the substrate ring, the electrode gap is not orthogonal to the ring. Due to the asymmetry arrangement of the surface electrodes and the electrode gaps, the electrode materials and the substrate materials with different thermal conductivity have no contact cross distribution with each other at the radial electrode gap. During welding, the heat shock is transmitted asymmetrically through the asymmetric electrodes, to improve the uniformity of the heat conduction distribution of the varistor and reduce the defective rate of the substrate welding fracture.

摘要： A magnetic material having dual properties and a manufacturing method thereof are disclosed. The magnetic material having dual properties consists of: 5% to 88% of a permanent magnetic material, 5% to 88% of a soft magnetic material, 6% to 16% of a binder, and 1% to 10% of an auxiliary agent. The magnetic material having dual properties manufactured by mixing two phases without microscopic intergranular exchange coupling interaction has unexpected effects: the range of a magnetically attracted object is expanded to include a magnet having dual properties; the range of a magnetically attractive object is expanded to include a magnet having dual properties; the minimum value of the magnetic attraction force is increased, the magnetic attraction force is more uniform, and it is smoother to move and rotate an object. The effect obtained by two layers of the soft magnet and the permanent magnet can be realized by a single layer structure of the magnet having dual properties.
