电起动马达的选型及应用

Type Selection and Application of Electric Starting Motor

电起动是目前广泛应用于中小型内燃机的一种起动方式。本文简要介绍了电起动的主要优缺点,在电起动马达的起动能力计算方面,主要对内燃机起动最低转速的选取、起动阻力矩及起动功率的计算作了简要说明,提出了对电起动马达的选择要求。对于电起动马达在内燃机领域的实际应用,推荐了电起动马达用蓄电池容量的选取方法及连接导线截面参数,介绍了电起动马达的安装及接线方式,着重强调了电起动马达在使用过程中的诸多注意事项。

Electric starting method is widespread used for medium and small size diesel engine nowadays. The paper briefly introduces the advantages and disadvantages of electric starting and the requirements on the selection of electric starting motor. On the calculation of starting capability of electric starting motor, it mainly states the determination of minimum starting speed and calculation of starting - up torque and starting- up power. According to the application of starting motor for diesel engine, this paper shows the way to select accumulator capability and the cross - section parameters of cormeeting wires, the method of installation and wire connection of the starting motor, and many precautions during the operation of the starting motor.
