Product Overview
The MW(Z) Electromagnetic Drum Brake is a widely used braking device in lifting, transportation and other industrial fields, featuring safety, reliability, energy efficiency and environmental friendliness. A full range of models is available, including MW(Z) 160-80, MW(Z) 200-160, MW(Z) 315-630, MW(Z) 400-1250 and MW(Z) 500-2500. In the model designations, numerical values such as 160 and 200 indicate the brake wheel diameter (in mm), while subsequent values such as 80 and 160 refer to the braking torque (in N·m). The brake is designed as a normally closed unit by default: when de-energized, the brake spring forces the brake linings to clamp the brake wheel tightly, achieving braking; when energized, the electromagnet generates a magnetic field that attracts the armature, overcoming the spring force to separate the brake linings from the brake wheel and allowing the equipment to operate normally.
