Product Description
The motor sets for excavator (shovel) is composed of lifting motor, thrusting motor, turning motor and stroking motor, CRRC Yongji Electric successfully developed motor sets for 4m3,10m3,12m3,20m3,27m3,35m3,55m3 and
75m3 excavator (electric shovel) as well as motor sets for 12m3 and 35m3 plateau excavator (electric shovel), the market share is more than 95%. The motor sets for 75m3 excavator (electric shovel)have advanced technology and excellent performance, which represents the frontier level in the field of motor for excavator.
The features of the motors for excavator (shovel)
·Improve and optimize the insulation structure and painting process to ensure the safe and reliable operation of the motors in various harsh environments such as wind and sand, rain and snow, high temperature and high humidity.
·The push-pull type dual-pulse output speed sensor can accurately transmit the speed signal to the control system, the speed sensor adopts Honeywell elements can ensure the stable output under bad working conditions.
·The specially designed bearing insulation structure can effectively weaken the corrosion of the shaft current to the motor and improve the bearing life. The sensor is set at the bearing position, which can send a warning signal before the motor failure, and can cut off the power supply in the fault moment to avoid greater loss.
