Frequently Asked Questions

What thermal limit should I respect when continuously applying 24 Nm at standstill?

The motor must not exceed its winding temperature limit (typically set via internal PTC sensor) — sustained standstill torque heats the windings and reduces safe duty time. Use the controller’s thermal monitoring or limit duty cycles to avoid thermal overload.

How should I size a coupling given the keyway shaft and centering diameter of 110 mm?

Use a coupling rated for the centering diameter plus dynamic torque—in practice select a high-stiffness coupling whose bore matches the keyway shaft, and account for torque peaks beyond 24 Nm. Also verify alignment tolerances to avoid radial or angular misalignment stress on bearings.

What impact does the side-A connector orientation have on cable routing and service?

Side-A connection fixes where power and feedback cables exit, so cable bends, strain relief, and shielding must be designed accordingly. Altering connector direction after delivery is not generally possible per the motor design.

Is balancing class important for high-speed or spindle-like applications?

Yes — MDD 093 motors are balanced to “reduced” class by default, suitable for moderate-speed applications; for very high dynamic or spindle use, confirm if a “reduced R” or custom balance option is needed.

What are typical B2B use cases that suit this motor’s characteristics?

It is ideal in packaging and printing lines for indexing rotary tables, in pick-and-place robots requiring high torque at low speeds, and in servo-driven conveyors needing precise start/stop control. Its high standstill torque and brake make it suitable where the load must hold position without drift.
