Treadmill Motor DC Permanent Magnet Universal Engine 180V 1-3HP. VOLTS (V) 180 d.c, R.P.M 3800/4800, INS.F, POWER (HP) 3.0, AMPS (A) 5.5, WEIGHT (kg) 7.3. Dimensions: A: 110mm, B: 103mm, C: 45mm, D: 265mm. When ordering a motor, please provide the dimensions A, B, C, D and a photo of your old motor. Our motor can replace your original model, but may not be identical in appearance. Note: 1. It is recommended to apply special silicone oil under the treadmill running belt every half month to maintain lubrication and reduce resistance. Use the treadmill at a faster running speed rather than slow walking to help extend its service life. 2. Recommended usage: operate for 30 minutes, rest for 30 minutes, then continue for another 30 minutes, followed by another 30-minute rest period. 3. Operation below 5 km/h is considered ultra-low speed, which results in poor motor heat dissipation and may cause overheating. Running at this speed should not exceed one minute. If low-speed operation is necessary, limit it to a few minutes and increase speed to over 7 km/h as soon as possible. 4. The motor can run continuously for up to 120 minutes at speeds above 7 km/h. Following these guidelines helps prevent motor damage. Product Specifications: 1. Maximum working voltage must not exceed rated voltage; voltage ripple should be minimized. 2. Motor wiring: red wire connects to positive, black wire to negative, yellow/green wire is for grounding. 3. Reliable grounding of the motor is required. 4. Under normal conditions, the motor terminals and end cover can withstand an AC 1800V, 50Hz, 5mA, 1-second dielectric test without breakdown. 5. When operating at rated voltage, the motor should show no abnormal vibration or noise. 6. Rotation direction: clockwise when viewed from the drive end. 7. At no-load operation, motor performance meets specified requirements.
