What is a Stepper Motor in Automobiles?

[LaVivian]

A stepper motor is an open-loop control element that converts electrical pulse signals into angular or linear displacement. Under non-overload conditions, the motor's speed and stopping position depend solely on the frequency and number of pulses, unaffected by load variations. When the stepper driver receives a pulse signal, it drives the stepper motor to rotate a fixed angle in the set direction. The following are hazards of vehicle overload: 1. Increased risk of rollover: The more overloaded passengers, the more the vehicle's center of gravity shifts, making rollovers more likely, especially during turns. 2. Reduced braking performance: Inertia relates to object mass. During braking, the vehicle relies on resistance to stop. Greater overload means greater inertia, making stopping more difficult than usual. 3. Tire blowouts: Overloading keeps tires operating under excessive stress, increasing tire pressure and temperature, which easily leads to blowouts. 4. Worsened accident outcomes: Normally, each occupant has corresponding safety belts and seats, but overload means not everyone is properly equipped. In accidents, otherwise avoidable situations become unavoidable.
