Answer :
Final answer:
The stepping angle for the hybrid stepping motor described is calculated by dividing 360° by the LCM of the rotor teeth and pole teeth, resulting in a stepping angle of 6° per step. Therefore the correct option is B
Explanation:
To calculate the stepping angle of a hybrid stepping motor with eight poles and six teeth each, and a rotor with 60 teeth, we can use the following approach:
- Firstly, we need to understand that each step moves the rotor from one tooth to the next, which implies that one step equals the angle subtended by one tooth.
- To find the stepping angle, we divide the total number of degrees in a circle, 360°, by the total number of steps the motor takes to complete one full revolution. This number of steps is determined by the least common multiple (LCM) of the number of rotor teeth and the number of teeth on one pole.
- The LCM of 60 and 6 is 60, which means the motor takes 60 steps per revolution.
- Therefore, the stepping angle is calculated as 360° divided by 60, giving us 6° per step.
The correct stepping angle for this hybrid stepping motor is 6°, which corresponds to choice B (3°) being incorrect.
