Synchronize and control-these are what a stepper motor does to your car's electronic system. This device is responsible for several aspects of your car's operation, including air-fuel regulation and meter reading. A stepper motor is up for replacement if it is already old and fails to provide accurate gauge readings for fuel, speed, temperature, oil pressure, voltage, and shaft rotation. You as a responsible driver cannot ignore the need for meter reading accuracy, so here are some pointers to keep in mind when shopping for a new stepper motor.
First things first: Stepper motor properties
Take out your car's specifications document before taking a shopping cruise online. Locate the page that discusses the details about the gauges in your car. Check the digits specified for the model of the stepper motor that must be used for the gauges. Next, check the properties of the motor you need. Stepper motors have a certain step angle that determines the degree to which the shaft turns once the signal from the control circuitry is received. The number of steps can be 100, 200, or 400, depending on the precision level. Systems that require higher precision will have a higher number. There is also a winding scheme, which can be bipolar or unipolar. This determines the type of control needed; buy a bipolar type if your system needs a simpler control. Other things you need to check are torque output, phase number (single, two, or four), and power requirements.
In addition to the mentioned specs, it is also advisable to look for stepper motors that are resistant to heat. The motors will sit underneath the gauge cluster on the dashboard, and it is certainly stuffy there. Stepper motors have parts that are made from plastic and aluminum, so maintenance is rarely necessary. These are also cheap, which is why they are sold in bulk. Also, stepper motors available at online auto parts stores are suitable for a wide range of models and makes, but you must purchase those that are specific to the series and engine type of your car.
