The E°SU3-030-E4-30-21-BK0 is a digital compact synchronous servo motor (230 V) from Eckelmann FCS for high-precision positioning tasks in the cost-effective segment. Together with the drive controllers of the E°Darc product family, the E°SU3-030-E4-30-21-BK0 forms a highly dynamic, compact servo drive unit for machine and plant engineering. The motor stands out for its excellent price-performance ratio, high dynamics and long service life.
Electronic commutation
It is a permanent-magnet motor with sinusoidal electronic commutation. An incremental or absolute encoder is used as the feedback system, providing precise position feedback. This ensures smooth, even running and high control quality even at low speeds.
Compact design
Thanks to its compact design (frame size 30, flange 60 mm), this servo motor is ideal for applications with limited installation space. Typical applications include handling, dosing and positioning tasks in industrial automation.
High operational reliability
The brushless design and grease-lubricated bearings ensure very high operational reliability over the entire service life. Low-maintenance components reduce downtime and lower operating costs. The motors are rated to a high protection class (IP65).
