This series of electromagnetic power-off brake is powered on and electromagnetic attraction. When power is off, the spring is pressurized to realize friction braking. It is mainly matched with Y series motor to form YEJ series electromagnetic braking three-phase asynchronous motor. It is suitable for metallurgy, construction, chemical industry, food, machine tool, packaging, stage, elevator, ship and other machinery to realize the purposes of rapid parking, accurate positioning and safe braking.

Product structure and working principle

Dltz3 series electromagnetic power-off brake product details: dltz3 series electromagnetic power-off brake is a friction brake with electromagnetic disengagement (release) and power-off spring pressure, which can realize rapid parking and accurate positioning, and can be used in safe (risk-proof) braking when there is no power.

The brake is composed of magnetic yoke, excitation coil, spring, brake disc, armature, gear sleeve, manual release device, mounting screw and other parts. When the brake coil is energized, the coil generates a magnetic field to attract the armature to the yoke, and the armature is connected with the brake disc
