Brake Motors


  • 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.


AMS SERIES - Low torque, DC Brake: fitted with a DC brake with a single braking surface and low torque (Mf ≤Mn). Due to the fact that it is a low torque DC brake, it offers quiet and gentle progressive braking, allowing it to brake large masses safely and slowly. When stopped it makes an ideal parking brake.


The brake has a fixed braking torque and uses its cast iron fan as part of the brake, this allows the motor to be only slightly longer than a motor without brake enabling it to be fitted on machinery without modification.
