  • Options make motors suitable for either onshore or offshore duties
  • Engineered to give high performance with maximum efficiency
  • Reliability & durability ensured through total control over components

Series AMBZ - asynchronous motors fitted with a three-phase AC brake with double braking surface and step-adjustable high braking torque (Mf>1.5Mn) to ensure precise and reliable braking.

This series offers fast and powerful braking typical of AC brakes and is the perfect series for all general industry applications requiring highest starting and/or braking frequency. The series is designed with separate brake power supply on a dedicated terminal board and avoids the user having to make changes due to the switching of the power supply system e.g. with soft starter or inverter.

Standard specifications:

  • Power: 0.12 to 22kW;
  • Frame sizes: 63 to 160;
  • Poles: 2, 4, 6, 8 (two speed on demand);
  • Insulation class F;
  • Degree of protection: IP54, IP55 and IP56;
  • Efficiency level IE1 or IE2;
  • Braking torque: 1.8 to 250Nm;
  • Spring-applied electromagnetic brake;
  • Brake discs with double braking surface;
  • Brake power supply: 230/400V 50Hz on dedicated terminal board.


  • cURus certification;
  • Executions for yaw applications on wind turbines;
  • Silenced execution for theatres;
  • Executions with brake parts in stainless steel;
  • Eencoder mounting;
  • Axial forced-ventilation, brake hand release lever and flywheel;
  • Wide range of surface painting/finish.
