32. Difference between Stepper Motors and Servomotors | Industrial Robots

This lecture is part of a lecture series on Industrial Robots given by Mr. Manish Bansal for B.Tech students at Binary Institute.
Description
This video explains the difference between stepper motors and servomotors in the context of industrial robots and automation systems. It describes how stepper motors operate in open-loop mode, moving in discrete steps for precise position control without feedback, while servomotors use closed-loop control with sensors for higher accuracy, torque, and speed regulation. The comparison covers construction, control complexity, efficiency, torque-speed characteristics, and applications. The video highlights that stepper motors are ideal for low-cost, low-to-medium speed tasks like 3D printers, CNC machines, and pick-and-place systems, whereas servomotors are better for high-speed, high-precision applications such as robotic arms, automation lines, and advanced motion control systems.
