What is NEMA 23 Stepper Motor?

The NEMA23 standard is indeed a motor size standard that is commonly used in various applications, including CNC machine tools, 3D printers, and robots, where high precision and high torque are required. The physical dimensions of a NEMA23 standard motor are generally 57.15 mm (2.25 inches) square with a shaft diameter of 6.35 mm (0.25 … Read more

Closed loop stepper motor Vs Servo

Closed-loop stepper motors are stepper motors with high-precision encoders and servo control algorithms to achieve torque, speed, and position loops. Is a closed-loop stepper a servo? The closed-loop stepper motor is a stepper motor, it has all the functional characteristics of a stepper motor. The biggest difference between stepper motors and servo motors is that … Read more


A variable frequency drive (VFD) is an electronic device that is used to control the speed and torque of an AC electric motor. It does this by adjusting the frequency and voltage of the power supplied to the motor. A VFD that has a single-phase input can be used to control a three-phase motor by … Read more

Stepper Motor Driver

The stepper motor driver is an actuator that converts electrical pulses into angular displacement. When the stepper driver receives a pulse signal, it drives the stepper motor to rotate a fixed angle (called “step angle”) in a set direction, and its rotation runs step by step at a fixed angle. The angular displacement can be … Read more

Panasonic Servo Alarm

Panasonic Servo Alarm 16.0 is overload protection. When the actual value of the torque command exceeds the overload level set by parameter Pr5.12, the overload protection function is activated according to the motor’s overload protection time limit characteristics.Alarm reason: The motor runs under heavy load for a long time, and its effective torque exceeds the … Read more

Stepper motor VS Servo motor

Why is it said that the stepper motor is an open loop, and the servo motor is a closed loop If the stepping motor adopts the servo-corresponding control method, it has most of the characteristics of the servo, but the cost is only 1/2 of the servo, and the servo does not have the problem … Read more
