Treadmill Motor DC Permanent Magnet Universal Engine 180V 1-3HP VOLTS (V): 180 DC R.P.M: 3800 or 4800 INS: F POWER (HP): 3.0 AMPS (A): 5.5 WEIGHT (kg): 7.3 1P CODE: 1P20 A: 110mm B: 103mm C: 45mm D: 265mm Notice: If you need to order a motor, please provide the dimensions A, B, C, D. Also, please provide a photo of your old motor. Our motors are designed to replace your existing motor. However, the replacement motor may not be identical to your original motor. NOTE: 1. It is recommended to apply silicone lubricant under the treadmill running belt every half month to maintain lubrication and reduce resistance. When using, operate in fast running mode rather than slow walking mode to help extend the treadmill's service life. 2. It is recommended to use for half an hour, rest for half an hour, then use for another half hour, followed by another rest period. 3. Speeds below 5 kilometers per hour are considered ultra-low speed operation, where motor heat dissipation is reduced. Prolonged use at this speed may cause overheating. Operation at ultra-low speed should not exceed one minute. If low-speed running is required, transition to a speed above 7 km/h as soon as possible. 4. The motor can run continuously for up to 120 minutes at speeds exceeding 7 kilometers per hour. Following these guidelines can help prevent premature motor damage. Product Specifications: Technical Requirements: 1. The maximum operating voltage of the motor must not exceed the rated voltage. Voltage ripple should be minimized. 2. Motor lead wires: Red wire connects to positive, black wire to negative, yellow or green wire is for grounding. 3. Motor grounding must be reliable. 4. Under normal conditions, the motor terminals and end cover can withstand an AC 1800V, 50Hz, 5mA, 1-second dielectric strength test without breakdown. 5. When operating at rated voltage, the motor should exhibit no abnormal vibration or unusual noise. 6. Viewed from the drive end, the motor rotates clockwise. 7. At no-load operation, motor performance meets specified requirements.
