Abstract
The utility model discloses a direct-current motor with multiple stator air channels, which relates to the technical field of direct-current motors. The motor comprises a stator core and a stator coil, the stator coil is wound on the stator core, and the air channels are arranged between the stator coil and the stator core. Since the air channels are formed between the stator coil and the stator core, the heat-dissipating area is enlarged, the heat dispersion is improved, the temperature rise of a motor stator is low, and thereby the service life of the motor is prolonged.
Description
Technical field
The utility model relates to a kind of technical field of DC motor, particularly a kind of technical field with the direct current machine in a plurality of air channels.
Background technology
Combine closely between existing DC motor stator core and the stator coil, gap useless between the two, this set causes the stator winding heat dissipation difficulty, and temperature rise is higher, and the insulation of motor is fragile, and shorten the useful life of motor.
The utility model content
Existing DC motor radiating effect is poor in order to solve, the problem of temperature rise, and the utility model provides a kind of stator multi-air-duct direct current motor.
The utility model comprises stator core, stator coil, and described stator coil is wrapped on the described stator core, between described stator coil and stator core the air channel is set.
Form a plurality of air channels between stator core of the present utility model and the stator coil, increased area of dissipation, improved heat dispersion; The temperature rise of motor stator is low, can adapt to than high ambient temperature (55 ℃) to press nominal load work down; Because temperature is low, slow with similar motor insulation ag(e)ing rate under same case, can improve the useful life in 2～3 years of motor relatively, raise the efficiency 0.5%～1.2%.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Among the figure, 1, stator core, 2, stator coil, 3, the air channel.
Embodiment
As shown in Figure 1, this DC motor comprises stator core 1, stator coil 2, and stator coil 2 is wrapped on the stator core 1, between stator coil 2 and stator core 1 air channel 3 is set.
Claims (1)
1. stator multi-air-duct direct current motor comprises stator core, stator coil, and described stator coil is wrapped on the described stator core, it is characterized in that between described stator coil and stator core the air channel being set.
