MBDV Hardware Manual
• It is recommended to use a disruptive coupling specially designed for servo motors, which can
provide some bu󰀨ering during eccentricity or deection.
• When installing the coupling, please wipe clean the anti-rust oil on the shaft end of the motor.
• When using the keyway, please use the standard key in the motor box.
• When installing a pulley on a servo motor with a keyway, use the threaded hole of the motor
shaft to squeeze the pulley into the motor shaft with a screw.
• When removing the pulley, please use professional tools such as pulley remover to prevent
bearing injury.
• When connecting the shafts, make sure to achieve the desired concentricity. If concentricity is
poor, the resulting vibration can damage bearings and encoders.
• The axial or radial load applied to the motor should not exceed the range specied in the
specications, please refer to the specication table of each servo motor.
• The material of the output shaft of the servo motor has no rust protection. Although grease
has been used for anti-rust protection before leaving the factory, if the storage time exceeds
six months, in order to ensure that the motor shaft is not rusted, please check the condition of
the motor shaft regularly every three months. And timely supplement the appropriate anti-rust
grease.
3.4.2 Precautions for motor in oil and water environment
• Do not allow oil and water to enter the inside of the motor
• Do not place cables in water or oil
• Since the through part of the motor shaft and the motor lead wires are not IP65 protected,
please ensure that no water or oil enters the motor from such parts
• The motor industrial grade skeleton oil seal can block pollutants (oil, impurities) to prolong the
life of the motor. When leaving the factory, the oil seal will be attached to the box, but will not be
installed on the motor output shaft. After the oil seal is installed, the oil seal will cause a certain
resistance and torque loss to the rotation of the motor shaft. It is recommended that the motor
be dated.
• In the application with liquid, please install the motor wiring port downward
