美国行业标准的试验步骤规定用定时电机和齿轮箱把被试马达的输出转速调节成1转/分。在制造商的最低推荐工作压力、半额定压力、满额定压力及最高允许工作压力下从力矩传感器(通常是一根标准力矩轴)取得力矩读数。虽然这种方法对于高速马达来说是令人满意的,但很多人争论说它不能准确地测定低速马达的起动力矩。 American industry standard test procedures require the use of timing motors and gearboxes to test the motor output speed is adjusted to 1 rev / min. Torque readings are taken from the torque sensor (usually a standard torque shaft) at the manufacturer’s recommended minimum working pressure, semi-rated pressure, full rated pressure and maximum allowable working pressure. Although this method is satisfactory for high speed motors, many people argue that it can not accurately measure the starting torque of low speed motors.
