Which type of electric motor do you size for your conveyor, XYZ table, or robot? Before you select one, you must understand the characteristics of each type of motor in the market.
Welcome to Oriental Motor's "Engineering Notes" Blog:
Products and technology are only valuable when coupled with skilled people and services to support them. ORIENTAL MOTOR U.S.A. CORP. has dedicated over 33 years to establishing a service and support system to better serve customers. It is our goal to provide the best product and service from the design phase, through the sale and beyond.
Our blog will feature:
- Introductions to New Products and Technology
- Application Examples, Improvements and Problem Solving
- Tips and Recommendations for Motor Selection, Installation and Use
In this blog post, I will explain how to easily program a timed pressing operation with our MEXE02 universal product support software. This example works for any products included in the AlphaStep AZ Series family, which also includes other series that use the same technology and software.
When a voltage is applied to an AC induction motor, it runs at a certain speed. Variable speed requirements for AC induction motors are typically fulfilled by a 3-phase motor and an inverter or VFD. This blog post also introduces another option.
There are three main types of stepper motors available in the market: PM (permanent magnet) type, VR (variable reluctance) type, and hybrid type. What are the differences, which one should you use, and how do they work?
No matter how many functions a product offers, without an intuitive, easy-to-use software, those functions can be difficult to implement.
An easy way to alter the speed and torque characteristics of a stepper motor is to connect it to a different type of driver or change its wiring configuration. However, there's more to it. Knowing the pros and cons between "unipolar" and "bipolar" can make or break your stepper motor performance.
For someone who has never had experience wiring I/O for motion control, it can be scary the first time. If devices are not wired correctly, it can cause a range of issues from a motor simply not doing what's expected to irreversible product damage. I still get that nervous feeling before I press the START button on a demo. Murphy's Law, anyone?
The significance of position control accuracy of motors varies depending on the application. For an AGV in a farm with DC motor-driven wheels, position control accuracy is probably not as crucial as a surgical robot where incisions are controlled by servo motors or stepper motors.
Besides load torque, acceleration torque, speed, and load inertia, overlooking certain sizing parameters during the motor sizing process can literally make or break your machine.
