Last Updated: 6th June, 2020
Electronic speedometers can also display speeds with analog pointers and dials, just like traditional eddy-current speedos: in that case, the electronic circuit drives a highly controllable electric motor (called a stepper motor) that rotates the pointer through an appropriate angle.

Regarding this, how does a stepper motor work?
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.
Secondly, what is a stepper gauge? Description. These stepper motors are often used in gauges for motorcycles and cars to replace the old-style fully-analog type. They have extremely fine step precision of about 1/2 a degree per step, 600 steps for single stepping, fast response for quick movements, and a range of 315° degrees.
Consequently, how does a stepper motor analog dash gauge work?
A stepper motor is a type of motor which can rotate in small steps depending upon the input signal provided to it. Analog displays on the dash uses stepper motor to move the needle. A discreet signal is provided to the motor which controls the rotation of the steps.
What is the principle of stepper motor?
Working of Permanent Magnet Stepper Motor The operation of this motor works on the principle that unlike poles attract each other and like poles repel each other. When the stator windings are excited with a DC supply, it produces magnetic flux and establishes the North and South poles.
