A variable frequency drive (VFD) is a motor driver for electromechanical drive systems that controls the speed and torque of an AC motor by varying the motor input frequency and controlling
Controlling stepper motors is a broad topic and this article is a simplified beginner's guide to use stepper motors. It covers the basics of how stepper motors operate. Its purpose is to help beginner..
A stepper motor is an electromechanical device converting electrical energy into mechanical power. At the same time, a stepper motor is a brushless, synchronous motor that can divide a full rotation i..
Although stepper motors have been characterized by their accurate positioning capability and high torque output at low speeds, they need carefully sized to ensure that the stepper motor is compatible ..
Planetary gearboxes are gear units extensively applied in industrial drive technology for their compact design and versatile applications. Since planetary gears are not mounted in a stationary positio..
When an incremental encoder rotates, two square wave outputs A and B are generated. These signals together form the quadrature output of the incremental encoder. These square waves A and B are 90 degr..
There are two types of DC motors in common use: brushed DC motor, and brushless DC motor (or BLDC motor). The name brushless DC motor is relative to the brushed DC motor. Brushed DC motor consists of ..
Brushless DC motors perform many of the functions that were originally performed by brushed DC motors. However, it is difficult to completely replace the brush DC motor because it is still an expensiv..
Brushless DC motor is a high performance motor, its biggest feature is that it has the external characteristics of DC motor but without the traditional contact commutators and brushes. It uses a perma..
A brushless direct current motor, abbreviated as brushless DC motor or BLDC motor, also known as an electronically commutated motor (ECM or EC motor) or synchronous DC motor, is a synchronous motor th..
1. What is the load of the system?
The load of the system includes static load and dynamic load, usually the size of the load determines the basic size of the motor.
Static load: the maximum thrust th..
