Criteria for selecting gear motors over 3.7kW

• Calculate required load and torque: Before selection, it is necessary to accurately determine the load, output torque, and working conditions of the system. This helps the gear motor operate at the correct capacity, avoiding overload or wasted investment costs.
• Select the appropriate gear ratio: The gear ratio determines the output speed of the gear motor. It is necessary to choose a gear ratio that meets the speed and traction requirements of the machinery to ensure efficient system operation.
• Consider working environment conditions: If the motor operates in an environment with high dust, high humidity, or extreme temperatures, you should choose products with an appropriate IP protection rating and corrosion-resistant manufacturing materials to enhance durability.
• Check continuous duty capability: For production lines operating 24/7, priority should be given to gear motors with continuous load capacity, high efficiency, and a good cooling system to ensure the equipment operates stably over the long term.
• Prioritize products with clear origins: Choosing gear motors from reputable brands and official distributors will help ensure quality, complete warranty policies, easy parts replacement, and technical support when needed.

Frequently asked questions?

What should be noted when installing gear motors over 3.7kW to avoid misalignment?

Before installation, it is necessary to check the concentricity between the gear motor shaft and the equipment shaft using a dial indicator or feeler gauge. Misalignment will increase vibration, generate noise, cause wear on bearings and couplings, and reduce the lifespan of the gearbox.

Is it necessary to check the lubricating oil before putting the gear motor into operation?

Yes. Before operation, it is necessary to check the oil level and lubricating oil type according to the manufacturer’s recommendations. If oil is insufficient or the wrong oil type is used, gears and bearings will not be fully lubricated, increasing friction, temperature, and the risk of gearbox damage.

Why is it necessary to use a suitable coupling when installing gear motors over 3.7kW?

A suitable coupling helps transmit torque effectively, compensate for small misalignments between the two shafts, and reduce shock loads upon startup. If the wrong type is selected or installed improperly, the system is prone to vibration, shaft wear, bearing failure, and reduced lifespan of the gear motor.
