Brake concepts

For rotating axes without any restriction on the angle of rotation < 360°, brake concepts are

only available that are individually designed for the drive.
The following aspects are decisive for a brake concept for drive systems based on segment

motors:

●

High moment of inertia

●

High speeds

●

Bearing design

If you need to stop the drive, for example when the power fails, the following

interrelationships make it more difficult to select a suitable brake concept:

Overvoltage protection using the VPM Voltage Protection Module
For a counter EMF Û > 820 V, overvoltage protection can be implemented using VPM

modules. However, the switch-on duration of the VPM is limited to 120 s for the rated and/or

short-circuit current of the VPM.
Generally, drives operating at high speeds and with high moments of inertia cannot be

stopped within 120 s using armature short circuiting of the VPM module.

Switching in short-circuit braking resistors
As a result of the high rated power of the drive, using short-circuit braking resistors requires

a lot of space.
Further, the drive speed range must be carefully coordinated. As a consequence, the braking

characteristic can only be optimized point by point.

Mechanical brake
If braking in the event of a power failure constitutes a critical operating point, then it may

make sense to use a mechanical brake.
Examples of critical operating points for an armature short-circuit include:

●

Cooling of the segment motor must be maintained so that it does not overheat.

●

For a drive with hydrostatic bearings or air bearings, the bearing fluid must be pumped

until the drive comes to a standstill so that the bearing system is not mechanically

damaged.

Contact the Application and Mechatronic Support group of Siemens to obtain in-depth advice

to obtain a customized, best possible solution for braking your drive system.
