技术领域technical field
本实用新型涉及一种串激电机。The utility model relates to a series excitation motor.
背景技术Background technique
家电行业中串激电机应用相当普遍，但大多采用铜漆包线，电机成本相对较高。以成本较低的铝漆包线取代铜线将使电机更具市场竞争力。Series motors are widely used in the home appliance industry, but most of them use copper enameled wires, and the cost of the motor is relatively high. Replacing copper wire with lower cost aluminum enameled wire will make the motor more competitive in the market.
串激电机风扇分离心式和轴流式两大类。用于高转速的轴流式风扇一般叶片数较多、外径较大，电机旋转运行时产生的噪音较高，风扇产生的功耗也较大。在大部份家电电机中，使用的仍是单一的温度保护，预极端状况时电机不能被有效保护，存在安全隐患。Series motor fans are divided into two categories: centrifugal type and axial flow type. Axial flow fans used for high speed generally have more blades and a larger outer diameter, and the noise generated when the motor rotates is relatively high, and the power consumption generated by the fan is also relatively large. In most home appliance motors, a single temperature protection is still used, and the motor cannot be effectively protected in pre-extreme conditions, posing safety hazards.

为了更好地理解和实施，下面结合附图详细说明本实用新型。For better understanding and implementation, the utility model will be described in detail below in conjunction with the accompanying drawings.
附图说明Description of drawings

图2是本实用新型风扇示意图。Fig. 2 is a schematic diagram of the fan of the present invention.
具体实施例specific embodiment
请参阅图1和图2，一种串激电机，该串激电机包括定子总成1和在其中转动的转子总成2，还包括换向片；所述定子总成1包括定子线包，该定子线包外表面设有铝漆层；所述转子总成2包括转子铁芯和换向片，所述转子铁芯设置有通槽，所述通槽数为换向片数的一半。还包括有转轴和冷却电机用的风扇3，所述转轴设置在定子总成中，所述风扇3设置在所述转轴上，所述风扇3中的叶片数为5片；所述风扇3为螺旋桨型。所述风扇3外周设有锯齿型导流筒31。所述风扇3为螺旋桨型。还包括有过流过热保护装置4，该过流过热保护装置4设置在电机内部。Please refer to Fig. 1 and Fig. 2, a series-excited motor, the series-excited motor includes a stator assembly 1 and a rotor assembly 2 rotating therein, and also includes a commutator segment; the stator assembly 1 includes a stator wire pack, The outer surface of the stator wire package is provided with an aluminum paint layer; the rotor assembly 2 includes a rotor core and commutator segments, the rotor core is provided with through slots, and the number of the through slots is half of the number of commutator segments. It also includes a rotating shaft and a fan 3 for cooling the motor, the rotating shaft is arranged in the stator assembly, the fan 3 is arranged on the rotating shaft, and the number of blades in the fan 3 is 5; the fan 3 is propeller type. The outer periphery of the fan 3 is provided with a sawtooth-shaped guide tube 31 . The fan 3 is a propeller type. It also includes an overcurrent and overheat protection device 4, which is arranged inside the motor.
本实施例中串激电机定子总成1采用纯铝漆包线；转子总成2转子铁芯槽数是换向器片数的一半，采用大、小圈数绕组，利用同一槽中的线圈，一只超前换向，另一只正常换向，可减少它们之间的互感。电机运行火花等级小于一级，使电机EMI符合要求，寿命达100小时以上。而采用相同匝数绕组的常规电机，运行火花为二级，因换向火花造成电磁干扰较大，电机寿命也因换向火花大而变短。In this embodiment, the stator assembly 1 of the series-excited motor adopts pure aluminum enameled wire; the number of slots of the rotor core of the rotor assembly 2 is half of the number of commutator pieces, and windings with large and small turns are used, and coils in the same slot are used. Only lead commutation, the other normal commutation, can reduce the mutual inductance between them. The spark level of the motor is less than the first grade, so that the EMI of the motor meets the requirements, and the life span is more than 100 hours. However, for a conventional motor with the same winding number of turns, the running spark is secondary, and the electromagnetic interference caused by the commutation spark is relatively large, and the life of the motor is also shortened due to the large commutation spark.
风扇3采用了带锯齿型导流筒31，通风换气效果明显，改善了进风区域的来流均匀性，减少空气流产生的涡旋和分离流动。根据空气动力学理论，用于强风冷却的电机，从噪音角度考虑，叶片数宜少。冷却风扇3在保证风量与常规的风扇3一致前提下，改常规为10～12片的设计，采用少片设计，减少风扇3叶片数为5片，形状为螺旋桨型。The fan 3 adopts a sawtooth-shaped guide tube 31, which has obvious ventilation effect, improves the uniformity of incoming flow in the air intake area, and reduces the vortex and separation flow generated by the air flow. According to the theory of aerodynamics, the motor used for strong wind cooling should have fewer blades from the perspective of noise. Cooling fan 3 is under the premise of ensuring that the air volume is consistent with the conventional fan 3, and the conventional design is changed to 10-12 pieces, and a few-piece design is adopted to reduce the number of fan 3 blades to 5 pieces, and the shape is a propeller type.
本实用新型结构简单，成本低廉，通风换气效果明显，相比就有技术改善了进风区域的来流均匀性，而且低噪音，使用更安全可靠。The utility model has the advantages of simple structure, low cost and obvious ventilation effect. Compared with the prior art, the uniformity of incoming flow in the air inlet area is improved, and the utility model has low noise and is safer and more reliable in use.
