Garden Motors

A: Yes, we have 100% test before delivery.

A: If no stocks, it takes 7 to 15 working days to manufacture after receiving the advance payment. If in stock, 2-4 working days are
possible. But it depends on the exact products and quantity.

A: We could accept the payment by T/T, Paypal, Western Union,L/C, etc.

A: Generally, the decision reflects experience and the machine builder's and grease supplier's recommendations. Relubrication intervals for most rolling element bearings range from two weeks to two years although for many it is once a year during scheduled maintenance shutdowns.

A: Proper lubrication of motor components is crucial in preventing wear and tear, thereby extending the motor's lifespan. Lubrication schedules should be adhered to based on manufacturer recommendations, considering factors such as operating environment and motor load.

A: Another way to inspect the bearings is by pushing and pulling the shaft that the bearings attach to. The bearings should rotate smoothly and the shaft should be able to move smoothly as well. That said, if you hear any scraping or feel any friction, you might need to replace the bearings.

A: Operating Life:Brushed motor life is limited by the brush type and can attain 1,000 to 3,000 hours on average, while brushless motors can attain tens of thousands of hours on average, as there are no brushes to wear. The limiting factor is the wear on the bearings.

A: Electrical tests such as polarity checks and voltage level measurements.
Vibration tests to detect any imbalances or misalignments.
Thermal tests to monitor the motor's temperature to avoid overheating.
Dynamic tests to see how the motor performs in transient states.

A: Yes, electric motors can weaken over time. As motors age, they can experience a decline in performance, efficiency, and reliability. This can include: Power fluctuations, Difficulty starting up, Decreased speed, and Reduced power output.

A: A bad motor bearing typically makes a grinding, knocking, or rattling sound that increases in pitch and volume as the engine speed increases, often described as a "roar" or "whine," signifying significant wear and potential damage to the bearing components; this noise can also be accompanied by vibrations in the engine.
