hitachi ex60 swing motor

The hitachi ex60 swing motor in the full hydraulic excavator is the key component of the swing mechanism. It converts the oil pressure provided by the main pump into mechanical energy and inputs it to the reducer. The quality of its working performance will directly affect the rotation speed of the whole machine, and the driving torque, swing parking and parking brake are the keys to determine the productivity of the whole machine. Rotary motors are divided into two categories: low-speed high-torque motors and high-speed rotary motors. Low-speed and high-torque motors are rarely used in modern excavator slewing mechanisms due to their small size and heavy weight, while high-speed slewing motors are small in size and light in weight, which is convenient for the reasonable layout of the slewing mechanism, and can also meet different slewing speeds and rotations. Moment requirements, it is widely used.
