Description
Technical Field
The utility model relates to the field of torque motor parts, in particular to a rotor core punching sheet structure of a large-torque motor.
Background
The torque motor is a special motor with more poles, can still continuously run at low speed even in locked rotation (namely, the rotor cannot rotate), and cannot cause damage to the motor. In this mode of operation, the motor may provide a steady torque to the load (hence the name torque motor). The torque motor may also provide a torque (braking torque) opposite to the direction of operation. The shaft of the torque motor outputs power not at constant power but at constant torque.
The existing large-torque motor can generate a large amount of heat energy when in use, and the coil at the motor rotor core punching sheet is burnt out due to high temperature, so that the service life of the motor is greatly reduced, and in order to improve the service life of the motor, the large-torque motor rotor core punching sheet structure is provided.
Disclosure of Invention
The utility model aims to solve the problems that a large amount of heat energy is generated when the existing large-torque motor is used, and the coil at the motor rotor core punching sheet is burnt due to high temperature, so that the service life of the motor is greatly reduced, and provides a large-torque motor rotor core punching sheet structure.
The utility model adopts the following technical scheme: the utility model provides a big torsion motor rotor core towards piece structure, includes the rotor core body, the rotor core body is the ring setting, rotor core body inside wall evenly is provided with a plurality of connecting seat, the connecting seat terminal surface evenly runs through and is provided with three louvre, and the louvre runs through the rotor core body.
Wherein the cross section of the connecting seat is T-shaped.
And a gap is arranged between the adjacent connecting seats.
In summary, due to the adoption of the technical scheme, the beneficial effects of the utility model are as follows:
the utility model provides a large-torque motor rotor core punching sheet structure, which is characterized in that connecting seats are arranged on the inner side of a rotor core body, three connecting holes are formed in each connecting seat in a penetrating mode, and heat dissipation is carried out on the rotor core body and an internal stator through the connecting holes, so that the service life of a device is indirectly prolonged.

Legend description:
1. a rotor core body; 11. a connecting seat; 12. and the heat dissipation holes.
Detailed Description
The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.
Examples
As shown in fig. 1-3, a large torque motor rotor core punching sheet structure comprises a rotor core body 1, wherein the rotor core body 1 is in a circular ring arrangement, a plurality of connecting seats 11 are uniformly arranged on the inner side wall of the rotor core body 1, coils and the connecting seats 11 are wound and arranged on the inner side of the rotor core body 1, three radiating holes 12 are uniformly formed in the end faces of the connecting seats 11 in a penetrating manner, three radiating holes 12 are formed in the position of each connecting seat 11 in a penetrating manner, the rotor core body 1 and an inner stator are radiated through the plurality of radiating holes 12, and the radiating holes 12 penetrate through the rotor core body 1.
The cross section of the connecting seat 11 is T-shaped, and the shape of the connecting seat 11 is limited. A gap is provided between adjacent connection seats 11 through which the coil is wound.
Working principle: the coil and the connecting seat 11 are wound, a large amount of heat energy is generated when the rotor iron core body 1 and the internal stator of the coil work again, and the heat energy flows out along the heat dissipation holes 12 of the connecting seat 11, so that the motor is dissipated, the service life of the coil is prolonged, and the service life of the device is prolonged indirectly.
The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the utility model.
