Product Advantage FAQs
1. What is a stepper motor and how does it work?
A stepper motor is an electric motor that rotates in discrete steps, allowing precise control of position, speed, and direction without feedback in open-loop systems.
2. What are the main advantages of using a stepper motor?
Stepper motors offer high positioning accuracy, simple control, excellent holding torque, low cost, and high reliability.
3. What types of stepper motors are available?
Common types include permanent magnet (PM), variable reluctance (VR), and hybrid stepper motors, with hybrid types being the most widely used.
4. What is the standard step angle of a stepper motor?
Most stepper motors have a step angle of 1.8° (200 steps per revolution), with other options such as 0.9° available.
5. Can stepper motors provide high torque at low speeds?
Yes, stepper motors are well known for delivering high torque at low speeds, making them ideal for precise positioning tasks.
6. What is holding torque in a stepper motor?
Holding torque is the maximum torque a stepper motor can resist when energized but not rotating.
7. Are stepper motors suitable for continuous operation?
Yes, stepper motors can operate continuously when properly sized, driven, and cooled.
8. How do stepper motors compare to servo motors?
Stepper motors are simpler and more cost-effective, while servo motors offer higher speed, efficiency, and closed-loop control.
9. What role does a stepper motor driver play?
A stepper motor driver controls current and step timing, ensuring smooth motion, accurate positioning, and motor protection.
10. What industries commonly use stepper motors?
Stepper motors are widely used in CNC machines, 3D printers, robotics, medical devices, packaging equipment, and automation systems.
