Are all GM Stepper motors the same?
The same stepper motor drives all gauges in the instrument so it is best to replace them all. The majority of General Motors vehicle models from 2003 to 2006, and a few others, have the same motors in their instrument panels.
How do I know which stepper motor to use?
A Simple guide to identify the stepper motor you have. If 8 wires, it will probably be unipolar, 4 per coil. If 6 wires, probably unipolar, 3 for one coil and another 3 for the other. This means each coil has its own ground. If 5 wires, probably also unipolar.

What is a stepper motor gauge?
SMi™ Stepper motor gauges use a small electronic motor that only turns a tiny fraction of a rotation to drive the pointer. It is electronically controlled and is much more precise than the traditional mechanical instruments whose accuracy can be affected by many factors. Many professional race teams – NASCAR™, etc.
How long do stepper motors last?
The typical lifetime for a stepper motor is 10,000 operating hours. This approximates to 4.8 years; given the stepper motor operates one eight-hour shift per day. The lifetime of a stepper motor may vary in regards to user application and how rigorous the stepper motor is run.
Does a stepper motor know its position?
The Powerful Ability of Highly Reliable Stepper Motors The motor operates by accurately synchronizing with the pulse signal output from the controller to the driver, achieving highly accurate positioning and speed control.
What voltage is a stepper motor?
Stepper motors have a rated voltage and current. A typical stepper motor like our NEMA 17 might have a rated voltage of 2.8 Volts and a maximum current of 1.68 Amps. This basically means if you hook it up to 2.8 Volts it will draw 1.68 Amps.
Why do stepper motors need drivers?
A Stepper Motor Driver is the driver circuit that enables the stepper motor to function the way it does. For example, stepper motors require sufficient and controlled energy for phases in a precise sequence. Due to this, stepper motors are considered more advanced than the typical DC motor.
What is the major benefit of a stepper motor?
One of the biggest advantages of stepper motors is their relatively low cost and availability. Stepper motors offer flexibility in application for a wide range of applications because the design of the stepper motor provides a constant holding torque without the need for the motor to be powered.
How are stepper motors controlled?
A stepper motor converts a train of input pulses into a precisely defined increment in the mechanical shaft position, where each pulse moves the shaft through a fixed angle. Stepper motor control provides this input train of pulses to command the motor to move to the desired position or at the desired speed.
Are stepper motors AC or DC?
Stepper motors are DC motors that move in discrete steps. They have multiple coils that are organized in groups called “phases”. By energizing each phase in sequence, the motor will rotate, one step at a time. With a computer controlled stepping you can achieve very precise positioning and/or speed control.
What is the difference between a servo motor and a stepper motor?
The main difference between these motors comes from the overall pole count. Stepper motors have a high pole count, usually between 50 and 100. Servo motors have a low pole count – between 4 and 12. Servo motors require an encoder to adjust pulses for position control.
