ABOUT FMI
FMI motors are synchronous alternating-current frameless actuators featuring superior torque density. The brushless technology employed in the drives enables packing impressive power into a compact footprint while minimizing friction-induced power losses and ensuring noise- and spark-free operation. With low cogging torque, FMI-series products provide smooth rotation without jerkiness.
FMI engines are supplied as rotor and stator kits. They can be easily encapsulated into any housing you need and have versatile mounting configurations. It is a solution with direct drive with no end bells, or shaft, or bearing. Their integrating process is almost plug-and-run operation.
A consistent torque delivery in the available velocity span is maintained with the help of a know-how winding. Rare-earth magnets and the inrunner configuration contributes to better efficiency. Overheating is prevented by temperature-sensing built-in elements.
FEATURES
High torque density
Rotor’s rare-earth magnets generate magnetic fields that are twice stronger than ferrite ones. Even if rotation rates are slow, stable torque delivery is maintained by star winding.
Hollow-shaft design
FMI engines are easy to mount and assemble as they are supplied as rotor-and-stator kits without a shaft. Depending on application specifics, a variety of drive mechanism configurations are allowed.
Compact size and low weight
FMI motor has a small size, but it boasts a high power-to-weight ratio. You can easily fit direct-drive motors into tight spaces and they require no additional accessories or fitting for transmitting the moving force to driven machines.
Brushless commutation
Greater controllability of motor and higher torque-to-weight ratio are achieved with the minimization of power losses. Failure and maintenance rates are decreased as there are fewer wearable components.
AC synchronous operation
The principle of work is associated with slight noise, insignificant disturbance of electromagnets and smooth rotation at low cogging.
Integrated thermal sensor
FMI kits’ stator coils comprise elements with temperature sensors. Demagnetization is prevented by these devices ensuring engine cutoff at overheating.
Robotics Solutions
ROBOTICS
Frameless motors offer such advantages as high torque and remarkable power efficiency packed into a small body that is easy to built into robot joints. The engines comprise few wearable components, which results in decreased maintenance scope and costs. Designed mostly as composite rotor and stator kits, the drives support a variety of mounting options to allow versatile robotic configurations.
