Wiring method of motor open-phase protection

Stepper servo motors, as critical components in industrial automation, directly impact equipment performance through their stability and precision. However, in practical applications, motors may exhibit abnormalities due to parameter configuration, mechanical load, or environmental factors. This article provides systematic solutions for six typical issues, combined with real-world engineering cases, to help technicians quickly identify and resolve problems.1. Abnormal Motor Vibration and NoiseVi

Thermal Relays for Motor Overload Protection: Principles, Selection, and ApplicationIn motor control systems, fuses are primarily used for short-circuit protection. However, they cannot protect against overheating caused by prolonged overloading, frequent forward-reverse operation, or undervoltage operation. Currently, thermal relays are widely used for motor overload protection. A thermal relay is a protective device that operates based on the thermal effect of electric current, and is essentia

"Selecting a High-Quality Motor" – Remember the Six Key Steps Inspect (Look): Check the motor’s appearanceThe motor’s surface should have a smooth, even paint finish. The nameplate must be properly installed with complete and clear markings, including: model number, serial number, rated power, rated current, rated voltage, allowable temperature rise, connection method, speed, noise level, frequency, protection rating, weight, standard code, duty type, insulation class, manufacturing date, and ma

A single-stack variable reluctance stepper motor features a salient-pole stator with concentrated windings mounted directly on the stator poles. The number of phases is determined by the connection configuration of these windings, typically comprising three or four windings. The rotor is constructed from ferromagnetic material and contains no windings.Both the stator and rotor are made of high-quality, high-permeability magnetic materials, requiring only a small exciting current to produce a str
