The Bosch Rexroth Indramat synchronous motor R911262939 (MKD090B-047-KG1-KN) is a servo motor with a size 090 and B length, equipped with 047 winding code. It features a plain shaft with a shaft sealing ring, an integrated 11 Nm holding brake, and resolver feedback with an integrated multiturn absolute encoder for position detection beyond 4096 revolutions. The centering diameter is 110 mm, and power connection is on the side B terminal box. The motor has a continuous stall torque of 12.0 Nm, a theoretical maximum torque of 43.5 Nm, and a winding resistance of 1.2 ohms. Protection rating is IP65, motor mass is 14 kg, and voltage constant is 91 V/1000min⁻¹. Heat dissipation from the stator windings to the housing supports high overload capacity, and motor temperature monitoring is incorporated for overload protection.

Frequently Asked Questions

How does MKD090B-047-KG1-KN behave at zero speed?

It supplies 12.0 Nm continuous torque at standstill to resist external forces. This capacity keeps the axis steady during inspections.

How precise is multi-turn tracking on MKD090B-047-KG1-KN?

Absolute detection over >4096 revolutions preserves count through interruptions. This feature minimizes re-referencing after resets.

What influences inertia planning on MKD090B-047-KG1-KN?

A rotor moment of inertia of 43 × 10⁻⁴ kg·m² defines acceleration behavior. That value guides tuning for snappy yet stable motion.

How does protection aid reliability on MKD090B-047-KG1-KN?

IP65 protection resists dust ingress and low-pressure jets. This sealing supports operation near coolants and debris.

What wiring aspect should be noted for MKD090B-047-KG1-KN?

Connection direction on Side B dictates cable routing and bend relief. This orientation helps clear guards and adjacent equipment.

Internal Product Review

Bosch Rexroth's MKD090B-047-KG1-KN pairs predictable dynamics with durable construction for demanding axes. A holding brake basically streamlines safe stops and fixture changes between cycles. The design simply favors steady throughput, lowering maintenance interruptions across long production campaigns.
