Ironless Motor

The UF Series is built specifically to sustain very high continuous forces for its footprint, which is only marginally larger than that of the UC. It is exceptionally suited for applications with high duty cycles, for instance in the medical and semiconductor markets or for pick & place systems.

Peak force: 42.5 – 85 N
Continuous force: 19.5 – 39 N
Coil Units: UF3 – UF6
Magnet Yokes: UF72 – UF120

In contrast to iron core motors, these motors feature an ironless coil unit, so there is no attraction force or cogging between the coil unit and the magnet track. This gives ironless motors their light weight, superior precision, a linear force constant, and extremely dynamic velocity, acceleration, and deceleration. Continuous force ranges from 10N all the way up to 846N with a peak force of up to 4200N.

Advantages of ironless motors

• With high acceleration and dynamics, the outstanding force-to-mass ratio of the ironless coils enables unmatched system dynamics.
• No cogging, extremely low force ripple, the motors have no cogging effects. Offering smooth motion and position accuracy in your application.
• Approved for CE and ROHS
• Low thermal resistance. This allows good heat transfer and achieves an extremely high continuous force for all motors when using a descent-size heatsink or active cooling.

Many industries benefit, such as semiconductors, display, inspection/ultra-precision stages, medical / life science/lab automation, and optics.
