Brake Motors

THREE-PHASE DC BRAKE - HIGH TORQUE

  • 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 component supply chains

Extensive configuration options match motors to applications

The harsher the working environment the greater the demand on engineering standards, and non-standard then becomes the norm. Custom-design and engineering fulfil this need to give the reliability and performance demanded.


The Lafert Brake Motor series is engineered according to the client's specification. Total control over all aspects of production permits multiple design options including flanges, shafts, brakes plus optimum resistance to external agents and hostile environments for paints, seals, and magnet surfaces.

 

The result is a range of AC motors produced entirely in-house which incorporates Lafert’s own technical solutions for achieving high efficiency and performance, combined with the option for application-specific customization.

 

AMBY SERIES - High torque, DC Brake: fitted with a DC brake with double braking surface and have high step-adjustable braking torque (Mf>1.5Mn) this ensures precise and reliable braking.

 

The series offers very quiet and progressive braking typical of DC brakes and for this reason it is the recommended option for all industry applications where noise must be reduced or for executions with a very high number of starts/hour.
