Our Ironless Linear Motor offers unmatched smoothness and agility, ensuring precise motion control in applications where dynamic performance and precision are critical.
Mid-large force applications: Force range Fc: 73-365N, Fp: 250-1250N
High acceleration, high speed, submicron positioning accuracy and low power consumption
Very good heat dissipation performance
Digital hall module can be mounted directly on the coil unit of motor
No attraction force and cogging, high dynamic motion performances
Any length of high flex chain cables for motors can be made
