Instructions for Use
The motor is suitable for most servo control systems and variable speed regulation control links, and is compatible with most drivers. It must be noted that all parameters of the torque fed motor are within the performance requirements of the servo motor, and the specified waveform coefficients (using pure DC) should be used. When the waveform coefficient of the motor power supply exceeds the rated value, the rated value of the motor must be reduced.Pay attention to the current and speed limits on the nameplate during operation, and do not operate at overload for a long time. Overloading for 2 times should be less than 1 minute, and overloading for 3 or 5 times should not exceed 5 seconds.
(1) Wiring method
There is a wiring diagram on the connection box (or wiring markings on the connectors of each motor). Note that in a closed circuit, it is necessary to follow the instructions on the identification plateConnect the motor with polarity. Incorrect connections can cause the motor to overspeed, shake, and even burn out.
(2) Bearing
All servo motors use specially matched single row radial ball bearings with dual protection and permanent lubrication, which do not require maintenance under normal use conditions.
(3) Bearing capacity
The standard structure of the shaft extension is determined by the coupling transmission, and the shaft extension only bears pure circumferential force (i.e. rated torque) without additional force. If subjected to during use
Additional force, its bearing value can be consulted with our company.
Motor maintenance
(1) Daily maintenance of motor
The motor must maintain a clean environment and no water or oil should flow into the interior of the motor. The surface of the motor, especially the lead out part, should be regularly blown clean with compressed air. Please note that the motor power must be cut off during any cleaning work.
(2) Replacement of bearings
When the bearing experiences abnormal conditions or reaches the end of its service life, it should be replaced in a timely manner. The brand of the replaced bearing should be as similar as possible to the original bearing. The disassembly of bearings should use a special die for bearings, and the assembly of bearings should use cold pressing method, and heating method is strictly prohibited. The general steps for disassembling a motor are: wiring, encoder, brake, Hall assembly, rear cover of the main engine, front cover of the main engine, and separation of the main engine stator and rotor. Attention: When disassembling the motor, please do not separate the relative position between the rear end cover and the Hall plate, and remember the relative position between the Hall magnet or encoder and the rotor shaft.
