Frequently Asked Questions
What special considerations come with using motor MDD093D-N-040-N2L-130PL2 from Bosch Rexroth in a servo system?
Because its DSF (digital servo feedback) encodes rotor position internally, the drive must support that protocol and cannot use external incremental encoders without adaptation. Also, the motor is sealed and non-disassemblable in the field, so any repair must go through Bosch Rexroth (cannot simply open and rebuild).
With 24 Nm continuous torque at standstill, how many axis drops or loads can it hold during idle?
That torque is quite high for a servo motor at standstill, so it can resist substantial static loads without drift. But over prolonged idle periods, consider self-heating and wear on bearings or brake friction surfaces under load.
What mounting orientation or alignment tolerances should you respect, given the 130 mm centering diameter?
The motor is rated for installation in any orientation, but you must align precisely to avoid radial or axial forces exceeding bearing limits. The motor’s floating “A” bearing handles radial loads, while the “B” side fixed bearing handles axial loads as per design guidance.
During fast deceleration or faults, how is stopping forced and how does the drive interact with the blocking brake?
In synchronous systems, the DC bus dynamic braking in the drive will short the DC link to brake the motor to standstill even if electronics fail.
How does the balance class “reduced (R)” used for MDD-093 series influence vibration and spindle use?
MDD 093 motors are dynamically balanced to the reduced balance class (class R), which lowers vibration in high-speed or spindle-grade applications.
