Is it a problem if the motor gets rained on?

It is not a problem if the motor gets rained on, as the motor itself has waterproof functionality. Below is relevant information about electric vehicle motors: 1. Introduction: The electric vehicle motor converts electrical energy from the power source into mechanical energy, which drives the wheels and working devices either directly or through transmission mechanisms. It generally refers to any machine that can convert mechanical energy into electrical energy or vice versa, specifically including generators, electric machines, and motors. 2. Classification: Motors can be categorized by power source type into DC motors and AC motors. DC motors can be further divided into brushless DC motors and brushed DC motors based on their structure and working principles. They can also be classified into permanent magnet DC motors and electromagnetic DC motors. Permanent magnet DC motors are further categorized by material into rare-earth, ferrite, and AlNiCo permanent magnet DC motors. AC motors can be divided into single-phase motors and three-phase motors.

My electric car was still running fine after the last heavy rain, but the mechanic said it depends on the specific components. The drive motor is basically IP67 waterproof rated and can withstand being submerged in water for half an hour. However, if the motor controller gets soaked, it's prone to malfunction. Last time, a car in our neighborhood lost power after going through standing water because this component got flooded. It's recommended to check the chassis guard plate after rain, paying special attention to the aging condition of the sealing rings on the motor wiring harness connectors. For those older cars that have been running for seven or eight years, particular attention should be paid to the aging of sealing strips. It only costs about a hundred bucks to replace a new sealing ring at the repair shop, so don't skimp on this expense.

Actually, what electric vehicles fear most is water vapor infiltration after wading. My neighbor encountered this issue last month—after driving in the rain, they heard abnormal noises from the motor. When lifted on a hoist, it was found that the cooling grille was completely clogged with mud, affecting motor cooling. Now, they make sure to rinse the chassis cooling vents during car washes. Remember, if the water depth exceeds half the wheel hub, don't force your way through, as the motor controller on many models is installed relatively low. If you must cross deep water, it's advisable to contact after-sales service for an insulation check—safety of the high-voltage system comes first.

The new car's protection is indeed good, but my cousin's Tesla had a normal battery pack after wading last year, but the drive motor's sealing ring was deformed. The 4S shop said it might be due to temperature differences causing the sealant to crack. During the rainy season, it's recommended to check if the drainage holes on the motor casing are clogged every time you wash the car, especially in areas with a lot of dust. A mechanic taught me a practical trick: after rain, if the motor casing doesn't feel hot to the touch, it means the heat dissipation is normal. For cars over three years old, pay attention to the waterproof connectors of the motor's high-voltage wiring harness—those repairs aren't cheap.

I've seen too many cases of water-damaged vehicles in auto repair shops. The drive motor itself is waterproof, but the bearings are most afraid of water. A certain brand's hybrid vehicle squealed after rain, and upon disassembly, it was found that the bearings had rusted and seized. Now during maintenance, we always ask the technicians to check the sealant on the motor end covers. In fact, the amount of rainfall has limited impact; the key is the wading depth. The manual states a maximum wading depth of 30 cm, which refers to passing through at a constant speed. The impact force of driving through deep puddles during heavy rain is completely different, and the water pressure may break through the seals. It is recommended to clean the motor compartment before the rainy season.
