HBZ 80B 4 – Asynchronous Three‑Phase Brake Motor with D.C. Brake

The HBZ 80B 4 is an asynchronous three‑phase brake motor with a d.c. brake, part of the HBZ series designed for gearmotor applications. It features a double braking surface with braking torque proportioned to motor torque (Mt = 11 N m). The motor incorporates a multi‑voltage rectifier (RM1/RM2) that generates a pre‑set constant output voltage independent from input supply fluctuations, reducing energy consumption and coil heating. It is suitable for operation with inverters, offers IP 55 protection, and is designed for maximum reduced noise level and operation progressivity during starting and braking. The motor is particularly suitable for applications requiring regular and low‑noise starting and braking with good precision and a high number of starts, such as gearmotor assemblies.
