A DC electromagnet is an industrial control device composed of an excitation coil, an iron core, and an armature. It generates a stable magnetic field through a DC power supply to control mechanical movements. Its standard operating voltage is DC6V-DC220V. It features a fully enclosed double-shell design to enhance dust resistance, allowing for a maximum switching frequency of 120 times/minute with lower noise than AC electromagnets. The core advantages of this product are high reliability, long service life (up to 100 million operations), precise magnetic field control, and energy efficiency. It is widely used in industrial scenarios requiring stable force control, such as automated equipment, medical devices, and textile machinery. Through patented technologies such as thermistor series connection, it effectively solves the problem of overheating and burnout in traditional products.
A DC electromagnet consists of a yoke, a moving iron core, a stationary iron core, and an excitation coil, forming a closed magnetic circuit system. The yoke is made of soft magnetic material and is rigidly connected to a fixed support. The armature is linked to the actuator through a linkage mechanism and is attracted by magnetic force when energized, producing linear or rotational motion. The coil winding process directly affects the magnetic field strength; the U1146 model uses a double-layer dense winding process to increase the magnetic flux density by 17%. The patented technology incorporates a positive temperature coefficient thermistor, achieving overheat protection through a current negative feedback mechanism.
