Does a larger motor pulley rotate faster or a smaller one?

[SanKennedy]

If we're only considering the motor's rotational speed, the size of the motor pulley (large or small) doesn't affect it—the speed remains the same. However, when it comes to the driven mechanical equipment, a larger motor pulley will result in faster equipment rotation, while a smaller motor pulley will lead to slower equipment rotation. Below are some maintenance methods for electric motors: 1. Keep the operating environment dry: The motor surface should be kept clean, and the air intake should not be obstructed by dust, fibers, etc. 2. Identify faults: If the motor's thermal protection repeatedly triggers, determine whether the fault originates from the motor itself, overloading, or the protection device's setting being too low. Only after resolving the issue should the motor be put back into operation. 3. Ensure good lubrication during operation: Generally, after about 5,000 hours of operation, the motor's grease should be replenished or replaced. If bearing overheating or grease deterioration is observed during operation, replace the grease promptly. When replacing the grease, remove the old lubricant and clean the bearing and bearing cover's oil groove with gasoline.
