Description

一种新型大扭矩启动电机 技术领域
本实用新型涉及一种新型大扭矩启动电机。
背景技术
常见的电动机是由固态的定子和转子组成的， 普遍存在起动转矩偏小的缺点， 且如果电 机直接连带着工作机起动， 起动电流很大， 若发生堵转， 电流会更大， 这样会对电机造成很 大伤害。
发明内容
针对上述现有技术的不足， 本实用新型提供了一种输出转矩大、 不怕堵转的新型大扭矩 启动电机。
本实用新型是通过以下技术方案实现的：
一种新型大扭矩启动电机， 包括外壳， 涡轮、 导轮， 所述外壳上设有至少一个电磁泵， 所述电磁泵是 ώ中空的泵壳、 电极、 磁体构成的， 泵壳两端设有丌口， 电极、 磁体均设在泵 壳上。
所述外壳外表面上设有六个电磁泵， 六个电磁泵呈环形排列。
使用时， 给电磁泵提供直流电， 接好电极， 使电场与磁场相匹配（根据左手法则来判断）， 导电液体进入电磁泵时， 会在电场与磁场的作用下加速， 加速后的导电液体流出电磁泵后冲 击电机的涡轮， 使涡轮旋转， 从而传递了能量； 导电液体经过¾轮后， 流进导轮， 在导轮的 导流作用下， 又流进电磁泵， 周而复始地循环流动。
由于电磁泵可以将导电液体的加速到较高的速度， 而其他机器启动时转速是从零开始逐 渐增加的， 也就是涡轮转速较低， 因此输出转矩较大； 且传递能量的介质为液体， 不怕堵转。
本实用新型将液力变矩器的优点融合到电动机中， 使用电磁泵带动液体冲击涡轮输出旋 转动力， 使电机起动时虽然转速很低但却可以输出较大的转矩， 减少了对电机的伤害， 并且 具有更少的零部件和更低的故障率。 由于电磁泵本身效率偏低， 因此本实用新型非常适于启 动其它机器（尤其是需要大起动转矩的机器）， 而不适合长时间工作。 当然， 本实用新型的结 构特点也允许把电机体积做的很小， 以方便使用。 本实用新型具有输出转矩大、 不怕堵转、 使用方便、 使用效果好等优点。

图 3为电磁泵的断面图；

使用时， 需要启动电机时， 给电磁泵 2提供直流电， 接好电极 5， 使电场与磁场相匹配 (根据左手法则来判断）， 导电液体进入电磁泵 2时， 会在电场与磁场的作用下加速， 加速后 的导电液体流出电磁泵 2后冲击涡轮 3, 使涡轮 3旋转， 从而传递了能量； 导电液体经过涡 轮 3后， 流进导轮 4， 在导轮 4的导流作用下， 又流进电磁泵 2 , 周而复始地循环流动。
