Features and Advantages
(1) Low-speed function: no need to increase the deceleration device, and can realize stepless speed regulation.
(2) High torque: provide full torque, start without time and frequency limitations, especially suitable for full load restart conditions.
(3) Shock Load Resistance: Reliable, long-term continuous operation and long service life in harsh environments and working conditions.
(4) Easy to install and basically maintenance-free: directly on the driven shaft, high reliability, space saving
(5) Excellent controllability: precise positioning, slow rotation but smooth and fast response to acceleration and braking.
(6) Perfect function: when using two or more hydraulic motors, it provides perfect load distribution function or synchronization function.
Precautions for installation
(1) Reasonable and effective motor mounting is a prerequisite for prolonging the service life of the motor. Generally speaking, the screws on top of any mechanical parts have certain torque requirements. This ensures the tightening strength of the screws. Depending on the specifications of the screws and the materials used for installation, the size of the torque is also different. When installing, you need to use a torque wrench, so as to ensure that the tightness of each screw is equal, too high torque will make the screws produce metal fatigue, reducing the service life of the screws, too low torque will make the screws easy to loosen, and ultimately accidents will occur.
(2) When installing, it is necessary to clean the motor and torque arm joint surface and apply lubricant before installation. And the screws used should be cleaned and lubricated. Finally, install the instructions for reasonable installation.
