Difference Between Servo Motor and Stepper Motor

Getting the Right Stepper or Servo Motor for Electric Actuators As the shift to automation continues to gain momentum in the industrial sector, servo motors and stepper motors with electric actuators become ever more important. When selecting a motor for an application, it is the functions that are important, not necessarily the construction. Throughout this article we'll evaluate the characteristics of servo and stepper motors as they relate to linear motion. (Brushless DC motors will be considered servo motors for this article.) Torque vs. Speed Servos have a constant torque over their total usable range of speeds. So, if a servo motor has 1.2 Nm of torque at 10 rpm, then it also has 1.2 Nm of torque at 3,000 rpm. Steppers on the other hand, have their maximum torque at low or zero speed and it falls off quickly at the much lower speed of a servo. If a stepper has 3.4 Nm of torque at 1 rpm, it is not unusual to see a drop to 0.2 Nm at 1,200 rpm. Engineers should look at each motor’s torque curves to select the proper size motor for an application. Servos go faster than steppers no matter what the torque is. In some applications, this lets a gearbox be used with a servo to increase the torque for the application. The gearbox multiplies the torque by its ratio and the motor rpm will go up by the same ratio. Engineers should be careful not to exceed the motor’s maximum rpm. For example, a motor with a torque of 2.3 Nm at 500 rpm when used with a 3:1 gearbox will have a 6.9 Nm output, but the motor’s rpm will climb to 1,500 rpm to drive the gearbox. Steppers’ higher torque and lower speed curve generally mean they will not use a gearbox. Read on: https://lnkd.in/gx8FVstR

Stepper motors are a type of electric motor that move in discrete steps, making them ideal for applications requiring precise control of position and speed. Unlike conventional motors, which rotate continuously, stepper motors move in fixed increments, or "steps," which allows for fine control. Code: https://lnkd.in/gRB3uHPg

Stepper Motor Basics WHAT IS A STEP MOTOR? A step motor is a brushless DC electric motor that moves in precise angles, called steps, by converting a series of electrical pulses into rotational motion. They will not produce continuous motion from a continuous input voltage, and it will stay at a particular position as long as the power is “on”. Step motors are controlled with the use of discrete electrical pulse signals. Each pulse will rotate the step motor shaft by a fixed angle called a “step”. Lin Engineering step motors have several different step angles to choose from (0.45°, 0.9°, 1.8°). https://lnkd.in/e5rHHM-j #brushlessdcelectricmotor #steppermotor #brushlessdcmotor

Comparing Eight Different Types of Servo Motors to Stepper Motors While servo motors are often chosen as a high-performance alternative to stepper motors, their variety and specialized applications are less commonly understood. This article aims to explain the differences between the types of servo motors, enhancing your understanding of when and why to use each type.

What Is Stepper Motor A stepper motor is essentially a synchronous motor that divides a full rotation into a number of equal steps (around 200 steps). It is an electromechanical device which converts digital pulses into mechanical shaft rotation. Some key aspects of a stepper motor include: It has a rotor with permanent magnets and a stator that contains winding. The winding is divided into phases (often two or more). Each step is caused by the energizing of the motor's stator winding in a particular sequence. The rotor aligns itself to the nearest stator pole Advantages of Stepper Motor Some key advantages of using stepper motors include: Precise positioning over full or part rotation with high resolution. Excellent speed and position control in open loop systems without feedback devices. Disadvantages of Stepper Motor Some disadvantages include: produce less torque compared to brushed DC motors of similar size. Vibration and resonance are likely if not designed properly. #snsinstitutions #snsdesignthinking #snsdesignthinkers
