Abstract
The utility model relates to a double-rotor permanent magnetic motor which comprises a motor casing and a motor shaft, wherein a permanent magnetic rotor is mounted on the motor shaft, and a permanent magnetic stator is mounted in the motor casing corresponding to the permanent magnetic rotor; a start excitation rotor is also mounted on the motor shaft, and a start excitation stator is arranged corresponding to the start excitation rotor. The utility model has the advantages that the start current of the permanent magnetic motor can be decreased to a great extent so as to lower the requirements of the start motor for transformer equipment so as to decrease the mounting and use cost of the equipment.
Description
Technical field
The utility model relates to a kind of magneto, specifically a kind of synchronous magnetoelectric machine with a plurality of rotors.
Background technology
High-power permanent magnet motor, particularly synchronous magnetoelectric machine commonly used at present, the moment of its startup all needs very big current excitation, also needs the more powerful transformer of configuration accordingly, and common transformer then can not start such magneto at all.And the cost of transformer is along with the also exponentially growth of increase of voltage device power, so brought problem for the popularization of high-power permanent magnet motor.At the problems referred to above, if can design a kind of high-power permanent magnet motor, as long as can start with relative less current excitation, so only need to use common transformer just can realize, can reduce the cost of transformer so greatly, bring very wide prospect for the promotion and application of this kind magneto.
The utility model content
The purpose of this utility model provides a kind of dual rotor permanent magnetic motor, realizes adopting less current can reach the effect of starter motor, solves the problem that the magneto starting current is excessive, the related transformer equipment cost is too high commonly used.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of dual rotor permanent magnetic motor comprises casing and arbor, and p-m rotor is installed on arbor, and corresponding p-m rotor is equipped with permanent-magnet stator in casing inside, and the startup excitation rotor also is installed on arbor, and the corresponding excitation rotor that starts is provided with startup excitation stator.
The beneficial effects of the utility model are: can reduce the starting current of magneto significantly, thereby reduce the requirement of starter motor to transformer equipment, thereby reduce the cost of installation and use of equipment.
Description of drawings
With embodiment the utility model is described in further detail with reference to the accompanying drawings below.
Fig. 1 is the described dual rotor permanent magnetic motor structure chart of the utility model embodiment.
Among the figure:
1, casing; 2, arbor; 3, p-m rotor; 4, permanent-magnet stator; 5, start excitation rotor; 6, start the excitation stator.
Embodiment
As shown in Figure 1, a kind of dual rotor permanent magnetic motor comprises casing 1 and arbor 2, p-m rotor 3 is installed on arbor 2, corresponding p-m rotor 3 is equipped with permanent-magnet stator 4 in casing 1 inside, also is equipped with to start excitation rotor 5 on arbor 2, and the corresponding excitation rotor 5 that starts is provided with startup excitation stator 6.
Because startup excitation rotor 5 has been installed on arbor 2, when starting p-m rotor 3, starting excitation rotor 5 can give 2 one high pulling torques of arbor in moment, drives p-m rotor 3 moment minor rotation.Be equivalent to only start originally, come together to start by p-m rotor 3 and startup excitation rotor 5 now with p-m rotor 3.So just can reduce the starting current of p-m rotor 3 significantly, thereby reduce the requirement of starter motor, thereby reduce the cost of installation and use of equipment transformer equipment.
Claims (1)
1, a kind of dual rotor permanent magnetic motor comprises casing and arbor, and p-m rotor is installed on arbor, corresponding p-m rotor is equipped with permanent-magnet stator in casing inside, it is characterized in that, the startup excitation rotor also is installed on arbor, the corresponding excitation rotor that starts is provided with startup excitation stator.
