Product Description
Motors for Shield Tunneling Machine
 
In 2006, CRRC Yongji Electric begins to enter the field of tunnel shield machine. So far, it has independently developed more than 50 types of motors for tunnel shield machine, mainly forming a series of motors for driving cutter head of tunnel shield machine, mud pump and hydraulic pump. The motors we developed almost cover the main types of domestic tunnel shield machine, which can completely replace the importing motors.

CRRC Yongji Electric can supply motors with power range from 55 kW to 400 kW for cutter head of tunnel shield machine; 7.5kw~1100kw for mud pump and hydraulic pump of tunnel shield machine. The motors have the advantages of small size, light weight, wide speed regulation range and high insulation level.

Features of motors for driving cutter head of tunnel shield machine:
·Power supply by frequency converter, can achieve constant torque start, constant power operation, and can achieve large torque to  get rid of difficult condition according to the specific geological conditions.
