Kollmorgen (Seidel) DBL DBK Technical Data

The synchronous servomotors of the series DBL/DBK are brushless three phase motors for high quality servo applications. The servomotors have Neodymium permanent magnets in the rotor. Because of standarised flange and shaft measurements the gear fitting is no problem.

The motors are equipped with two-pole hollow-shaft resolver. As an alternative these motors are available with high-resolution encoders. Retrofitting is not possible. The length of the motor depends on the feedback type.

Holding Brake
The motor can be delivered with or without a built-in holding brake. Retrofitting is not possible. Themotor length will increase with an installed brake.

Coil temperature is supervised by temperature sensors and reported by potential free contacts.

Short motors
The motors of the series DBK are very suitable for room restricted installation areas.

The DBL motors are compatible with the proven 6SMx7 motor series.
