The Bosch Rexroth MPN R911273148 (MDD115A-N-020-N2L-130GR1) is an AC servo motor featuring a continuous standstill torque of 28.0 Nm, nominal speed of 2000 rpm, and a plain shaft with a shaft seal. It utilizes a digital servo feedback (DSF) system for speed and position control, compatible with both relative and absolute measurements. The motor incorporates a blocking brake with a holding torque of 45.0 Nm and has a centering diameter of 130 mm. Designed per DIN 40050, the enclosure provides protection against solid objects and water splash. Electronic commutation and pre-lubricated bearings are used to enhance operational lifespan and reduce wear. This unit is supplied with a connector type electrical connection in a rightward direction.

Frequently Asked Questions

How does the MDD115A-N-020-N2L-130GR1 manage precise positioning in servo applications?

Its digital servo feedback ensures accurate rotor position data, which enables fine motion control. This makes it suitable for CNC machines and automated assembly systems requiring repeatable accuracy.

What role does the holding brake torque play during machine shutdowns?

The 45 Nm brake torque locks the shaft to prevent unintentional movement. This is critical for safety in vertical load or suspended load applications.

Why is continuous torque at standstill important in motion systems?

It allows the motor to sustain load without rotation, maintaining force even when stationary. This reduces reliance on external clamping mechanisms in positioning tasks.

How does a shaft seal impact long-term reliability?

The seal prevents dust and oil ingress at the shaft entry point. This reduces bearing wear and extends motor service life in harsh environments.

What connection advantage does a right-side connector provide?

It standardizes cable routing in panel-mounted or confined layouts. This simplifies wiring and reduces strain on power and feedback cables.
