为适应工程钻机复杂地层施工要求,需选用具有高起动转矩、高过载能力的电动机。针对普通电动机驱动钻孔设备存在的不足,YDZ系列工程钻机用高转矩三相异步电动机采取不同措施进行了改进,如鼠笼转子及特殊形式的转子槽形以提高起动转矩、单绕组反相法变极调速方式进行恒功率调速、新型设计从而强化结构强度和密封效果等等。经过实际运行,该电动机可适用在各类钻机设备上。
To meet the construction requirements of complex drilling rig construction, the need to use a high starting torque, high overload capacity of the motor. In view of the shortcomings of ordinary motor-driven drilling equipment, YDZ series drilling rig uses high torque three-phase asynchronous motor to take different measures to be improved, such as squirrel cage rotor and special form of rotor slot to improve starting torque, single winding Phase method Pole pole speed regulation for constant power speed control, new design to strengthen the structural strength and sealing effect and so on. After the actual operation, the motor can be applied to all types of rig equipment.
