Product Description:

The 04.KD.301-003U is a synchronous servo motor produced by KEB and offered within the SM Synchronous Servo Motors series. As a closed-loop actuator, it converts electrical input into tightly regulated torque so that pick-and-place heads, miniature conveyors, or packaging spindles follow programmed motion profiles in industrial automation cells. Its electromagnetic design emphasizes stable speed under varying load and quick reversal capability, supporting modern servo drives that rely on encoder feedback for precise positioning.

The motor housing carries an IP65 ingress protection level, blocking dust and withstanding water jets during washdown or coolant splash. Installation is simplified by the face-mount flange coded B14, which uses a standardized pilot diameter and bolt circle for compact gear reducers. Connected to a 50 Hz grid, the unit supplies 0.18 kW of continuous mechanical power and reaches 1340 rpm, making it suitable for modest conveyors or feeders. These output figures apply under the intermittent duty cycle classified as S3-30%, where the motor runs for thirty percent of each cycle and then cools between duty periods to limit winding temperature. The stator is wound for 50 or 60 Hz mains and, at 50 Hz, it accepts line potentials of 230/400 V AC, allowing direct connection to common European control panels without an isolation transformer.

On 60 Hz supplies, the performance shifts: rated output climbs to 0.22 kW and nominal speed rises to 1630 rpm, enabling shorter indexing times in material-handling equipment. The required terminal voltage becomes 230/460 V AC, which is compatible with North American plant power. As a three-phase machine, it distributes magnetic flux evenly around the stator so torque ripple is minimized, which improves servo accuracy in cyclic positioning tasks. The dual-frequency wiring allows the same motor to be used with either regional supply arrangement while keeping the basic control approach unchanged.
