DRB rotary motor

Features are as follows: small volume, large power, stable speed, with a large load, the maximum static load 3OKN, large working pressure, the maximum pressure can reach 25MPA;

- Imported thrust bearing, can withstand large axial load;

Can be used for excavators, truck cranes, port machinery, wood grabber, steel grabber, cane grabber forestry machinery grabber, light weight, convenient disassembly and assembly, simple operation; one

Set rotary lifting in one, in the use of the process will not appear the situation of winding hose;

Suitable for equipment with rotating action, wide range of use.

    In the whole process of motor stator winding maintenance should be a second inspection experiment. One is dip paint drying treatment before, after. Because the electromagnetic coil winding is not fixed before dipping, it is very convenient to find the problem is very easy and convenient. After if dip paint drying is handled, the problem that discovers in detection goes solving again is very difficult. In the hydraulic gear motor stator winding three-phase voltage, current, inspection and electromagnetic oscillation experiment, immediately connected (380/220V) working voltage is not reasonable, are not safe. It is good to use auto-voltage regulator as switching power supply. When inspecting, the three-phase output end of auto-voltage regulator will be connected to the stator three-phase winding immediately (do not install the motor rotor). According to the size of the core diameter of the motor stator transformer, the central part of the stator core is placed with a steel ball around 0.5-1cm, and then the voltage regulator is rotated to gradually rise (the general current is operated at 36V). At this time, the steel ball of the hydraulic walking motor rotates under the effect of electromagnetic oscillation. Here, it can also test the three-phase voltage and current flow of the stator winding. This method can not only be trusted, but also can immediately check the temperature of the stator electromagnetic coil and other information transformation.
