Motor Description

When the pulley is assembled, hot sleeve method is allowed, but forced cooling is required to make the bearing temperature is not higher than 95℃. For YE4 series motor installed vertically, no other axial load devices are allowed for the shaft extension in addition to the belt pulley (or equal to the load of ordinary pulley). If the belt is too tight or installed improperly, the bearing will be heated and damaged, and the motor shaft may be bent and broken.
A good ventilation and cooling condition shall be ensured for the installation site of the motor. Keep away from sunshine and rain. The motor must be installed on a firm and solid foundation, and reliable grounding shall be ensured. The motor grounding mark is located in the special position in the outgoing box, and is equipped with good grounding pole. There is one or two grounding positions on h315-355 motor and some special designed motor bases (the grounding device is installed according to the special requirements of users).
