Brushless dc motor controller because of its high, service life and good controllability, and good effect of mute, has been widely used in many control areas. However, in many cases had to use a reducer, such as low speed, to get the speed of the motor controller is lower than 1000 turn, generally need to use reducer. And high torque, rely on the torque of the motor controller itself is limited, when we need a little high torque motor controller, have to use gear box to improve the torque. Gear box is short of the brushless dc motor controller board, if the gear box do bad, also can affect the use effect of the whole motor controller. Brushless dc gear motor controller installation and instructions are as follows: 1, the brushless dc motor controller is usually 3 -5 wire, positive and negative level cannot meet the, meet the will burn machine; 2, brushless motor controller cannot run overload for a long time, otherwise easy to burn machine; 3, brushless motor controller for precision electronic components, not violent collisions; 4, the speed of brushless dc motor controller by PWM speed regulating, rather than through the voltage control of motor speed, usually of the brushless dc motor controller voltage is constant. Brushless dc gear motor controller of gear box installation and instructions are as follows: 1, if you want to change the installation position of the gear motor controller, to the corresponding correct lubricating oil filling quantity. 2, use gear motor controller must abide by the provisions of the manual on, in strict accordance with the said on the manual operation; 3, deceleration motor controller in use process in the corresponding standards and procedures within the scope of work, must not beyond. 4, upon receipt of the product to check in time is damaged during transit, or the lack of parts, etc. , if there are any problems please contact the department of transportation. 5, all with the transportation, installation, commissioning, operation, maintenance and repair work, can only be made by qualified professionals in accordance with the relevant provisions. 6, deceleration motor controller do waste, enclosure, gear, shaft and bearing according to scrap processing. Part of the turbine is non-ferrous metal manufacturing, according to the environmental protection regulations, to correctly the collection and handling of the oil. 7, if the gear motor controller using incorrect appeared in the process of installation and use, installation, and operation behavior is not correct, not to install or dismantle protective cover and cover the behavior, will likely result in serious injuries and property losses. In dc gear motor controller WWW. 51 zh型。 Com in use process found deceleration motor controller appears unusual, it is necessary to stop the machine immediately to check and identify reasons: 1, deceleration motor controller had better be to adopt soft start, try to avoid full launch. 2, check the gear motor with no load controller steering direction should correctly, can monitor running sound is normal. 3, the requirements of the lubricating oil: TH, TB, TP series gear motor controller meets the requirements of lubricating oil will be listed before use. At the same time before work should check whether the oil amount is suitable. 4, deceleration motor controller in the first run for the first time or after major repair replacement parts must be in the formal work of no-load running, running in and time shall not be less than 24 h. 5, the right and wrong boot after careful observation reduction motor controller of sealing, noise, vibration, temperature rise is normal, if malfunction should immediately stop, find out the reason, troubleshooting rear can continue to use. 6, TB series gear motor controller should take proper amount of lubricating oil lubrication in front of the boot shaft bearing.
