What is the resistance value of the clutch motor in the Benben Mini?
3 Answers
The resistance value of the clutch motor in the Benben Mini requires relevant permissions to query via OBD. Solutions for clutch burning: Go to a repair shop to check the clutch clearance and clutch pedal travel. The exact values depend on the mechanic's assessment. If you want to test it yourself, find an empty road, preferably in 2nd gear, fully release the clutch, and drive at 2500 to 3000 RPM. Then, while ensuring safety, press the accelerator to the floor without shifting gears. Observe the speed and RPM. If the RPM rises immediately but the speed doesn't, it indicates a loose clutch, meaning the clutch has been burning continuously. If the RPM is normal, stop the car, shift to 1st gear, release the handbrake, press the clutch, and rev the engine. If the car moves slightly, it means the clutch is too tight. Clutch slipping: If the clutch slips in a Changan Benben automatic transmission car, it might be due to low oil pressure, valve body sticking, friction plate wear, or clutch piston failure! Severe slipping may require a major transmission overhaul!
As an experienced tinkerer with electric vehicle circuits, I can tell you there's no fixed resistance value for the BenBen Mini's drive motor, as it varies significantly across different model years. Typically, motor resistance ranges from a few milliohms to one or two ohms, and accurate measurement requires a multimeter when the vehicle is cold. A sudden increase in resistance might indicate burnt coils or rusted contact points, which drastically reduces motor efficiency and causes noticeable power loss during uphill driving. The BenBen Mini is purely electric, so it doesn't have a traditional clutch concept. What some enthusiasts refer to as the 'clutch motor' is likely the drive motor assembly. Always consult the official repair manual or manufacturer data before testing to avoid short circuits. If you hear humming noises or experience jerky acceleration, prioritize safety and get a professional diagnosis at an authorized service center immediately.
After driving the BenBen Mini for so many years, I feel the term 'clutch' is a bit confusing. The resistance of the electric drive motor affects battery consumption. Last time, my car was slow to start, and the mechanic measured the resistance to be only 0.5 ohms, but it increased after aging, causing abnormal heating. Generally, a resistance of a few tenths of an ohm is normal. Too low indicates a risk of short circuit, while too high leads to poor power supply. It's recommended to ask the mechanic to check the motor terminals with a multimeter during maintenance, especially after rainy days when the wiring is prone to rust. If you're curious and want to try it yourself, buy an inexpensive multimeter and set it to the ohm range, but make sure to disconnect the power to prevent electric shock. The BenBen Mini motor is reliable, but if problems occur frequently, it's better to replace it with a new part for peace of mind, as the price is not expensive.
