Magnetek MST E Chapter 3.0: Application

Chapter 3.0: Application

3.1: The brake covered by this manual is type MST/E. This brake has an adjustable external torque spring and is generally applied on installations where the required torque cannot be predetermined within well defined limits.

3.2: For a given wheel diameter the Association of Iron and Steel Engineers (AISE) determines the prescribed torque, when applied to 30 and 60 minute rated motors in steel mill applications.

3.3: When applied to four quadrant drives or other applications where wheel heating can be accurately predicted, type MST/E brakes can be provided with torque values in excess of the AISE recommendations.

3.4: When the load cycle requires a larger than normal wheel size, as is frequently the case on crane bridge drive, MST/E brakes can be provided with torques lower than AISE for a given wheel size.

3.5: For applications where larger than normal running clearance is required, a larger actuator can be applied to a given brake. Typical would be severe applications where wheel expansion can be considerable or where excessive wheel run-out can be expected.
