Indramat ADF

Indramat ADF

The ADF series of main spindle motors are utilized for applications that require liquid-cooled main spindle drives and servo drives, such as tool machines, and have been successfully implemented in industries like printing, textile, and plastics injection molding.

These motors, when paired with drive controllers, boast a wide speed range and a field weakening range of 1:6, as shown by the diverse nominal power ratings in the graph, which range from 8.5 kW to 52 kW. They are equipped with motor feedback systems that ensure precise rotor position measurement and speed regulation with a resolution of one part in two million revolutions.

For safety and functionality, the ADF motors include a holding brake capable of clamping the output shaft at a standstill, with options for electrical actuation available. Additionally, they are designed to accommodate a shaft extension on the B side for the attachment of an additional position encoder, and are maintenance-free due to their induction principle design, optimized for flange mounting.

Applications

ADF motors are designed for critical applications in which precise control is necessary. For main spindle applications, an electrically-engaged holding brake serves as a locking element to secure the main spindle when idle or when the drive is disabled, such as during tool exchanges without active position control. The brake engages only after receiving a signal indicating the motor is stationary, ensuring safety and control.

It is advised against using an electrically-released holding brake in main spindle applications due to the risk of accidental engagement at high speeds, which could be triggered by power failures or wire breakages, potentially leading to the destruction of the brake.

In servo applications, the ADF motors use an electrically-released holding brake to maintain the position of linear axes when stationary and when the drive enable signal is inactive. For vertical axes, it is crucial not to disable the drive until after the brake has secured the mechanical system at a standstill. These brakes are designed to close occasionally in emergencies, such as power failures or emergency stops, as long as the action stays within the permitted braking energy range for the brake type. There is also a heavy-duty electrically-released holding brake available for demanding applications. However, the electrically-clamped holding brake is not recommended for servo applications, as it does not clamp the axis when there is no power.
