I. Mechanical Dimensions:
Maximum acceptable installation space, such as diameter, length, etc.
Screw dimensions for installation, including specifications, effective depth, spacing, etc.
Dimensions of the product's output shaft, flat screw, pin holes, positioning tabs, etc. Consider compatibility with the installation during product design. It is advisable to reserve a slightly larger assembly space for more model options.
II. Electrical Performance Selection:
Determine the rated torque and speed. If unsure of your requirements, you can estimate and purchase ready-made motors in the market for testing. Once validated, provide the supplier with the operating voltage and current.
Maximum allowable current and torque. While higher torque may seem better, excessive torque can damage the entire system, causing wear on mechanical structures and components, impacting the motor and gearbox lifespan.
When choosing electrical performance, opt for lower speed and smaller reduction ratios for a high-strength and long-lasting product.
III. Noise Considerations:
Mechanical noise is often the primary concern.
If the motor, when installed in the product, produces excessive noise, investigate potential causes such as resonances due to high rotation speed, resonance between the gearbox and mechanical components, or noise caused by eccentric loading.
Material selection plays a role; plastic gears generally produce less noise than metal gears. Helical gears are quieter than straight-cut gears. Turbine worm structures and planetary gearboxes in metal can contribute to higher noise levels. Precision in design and manufacturing can effectively reduce noise.
IV. Determine Priority Directions for Product Assurance:
Select different geared motors based on specific usage environments. For financial equipment, prioritize reliability; for toys, prioritize safety and eco-friendliness; for industrial products like valves, prioritize product lifespan; for household products, prioritize quiet operation.
Experienced engineers often tailor detailed products to meet customer requirements, considering factors beyond speed and torque.
In the diverse field of motor applications, professional expertise is crucial. Entrusting motor selection to skilled engineers can yield efficient results.
