Torque protection mechanism for brushless motor
A mechanism is capable of establishing a torque level to achieve torque protection of a brushless motor based on measurements of the rotational speed of the brushless motor without the need to use measurements of the drawn current. Accordingly, a rotational speed corresponding to a nominal torque has been established in advance such that the rotational speed is reduced when an over-torque exists. This makes it possible to estimate whether an over-torque is present, and therefore torque protection of the brushless motor is achieved efficiently, simply and very economically. The mechanism consists of: a power supply (1); a rotation direction setter (2); a control unit (3) connected to the rotation direction setter (2); a brushless motor (5) having a connection for sending an interrupt command from the control unit (3) to the motor (5), the interrupt command being a signal sent when operation is stopped due to overtorque.
一种机构能够在不需要使用对所汲取的电流的测量的情况下基于对无刷马达旋转速度的测量确立转矩水平来达成对无刷马达的转矩保护。因此，已预先确立与标称转矩对应的旋转速度，使得当存在过转矩时，减小所述旋转速度。此举使得能推测出是否存在过转矩，因此有效、简单且非常经济地实现对无刷马达的转矩保护。所述机构由以下各项构成：电力供应器(1)；旋转方向设定器(2)；控制单元(3)，其连接到所述旋转方向设定器(2)；无刷马达(5)，其具有用于将中断指令从所述控制单元(3)发送到所述马达(5)的连接件，所述中断指令是在由于过转矩而停止运行时发送的信号。
