Product description

Size 063B and natural-convection cooling characterize the Bosch Rexroth MAC063B-0-GS-4-C/095-A-1/WI520LV. This permanent-magnet AC servo motor belongs to the Indramat MAC series; its GS winding has a rated speed of 3,500 min⁻¹. Continuous torque at standstill is 1.5 Nm at a continuous current of 3.6 A. The torque constant is 0.42 Nm/A, while the winding has a resistance of 4.1 Ω and an inductance of 3.9 mH. The maximum pulse current is 19 A. Type-code position 4 denotes tacho feedback with a mounted incremental or absolute encoder. WI520LV identifies the mounted encoder code. The power connection is located on side A of the housing, and the centering diameter is 95 mm. An electrically released holding brake with 3 Nm holding torque, 24 V DC rated voltage, and 0.6 A rated current is part of this version. The thermal time constant for natural cooling is 30 minutes. The motor housing has IP65 protection and insulation class F. The permitted ambient temperature range is 0 to +45 °C. Storage and transport temperatures are -20 to +80 °C, and the maximum installation elevation is 1,000 m. Encoder version 4 and the holding brake extend dimension A of size 063B to 202.5 mm. The motor weighs 3.9 kg. The combination of GS winding, 95-mm centering, connection side A, brake, and encoder code distinguishes this MAC-063 version.

What winding and torque data apply to the Bosch Rexroth MAC063B-0-GS?

The GS winding of size 063B is rated for 3,500 min⁻¹. Continuous torque at standstill is 1.5 Nm at 3.6 A, and the torque constant is 0.42 Nm/A.

Which encoder and brake version does the MAC063B-0-GS-4-C/095-A-1/WI520LV have?

Type-code position 4 denotes tacho feedback with a mounted encoder, here with code WI520LV. Position 1 denotes the electrically released holding brake with 3 Nm, 24 V DC, and 0.6 A.

What applies if an item develops a defect within 14 days?

For the condition categories “Used, removed from an installation” and “New, old stock”, the contractual 14-day right of return in the event of a defect applies. The defect must occur within 14 calendar days after delivery and be reported in text form within the same period.

In particular, the REHA tamper-evident seal must remain fully intact and our RMA approval is required before return. In an accepted case, we decide between replacement and refund. Details in Section 11 of the Terms.

Which shipping methods and delivery times are available?

The shipping method, shipping cost and estimated delivery time are confirmed for the specific order. Depending on the item, destination and urgency, we can check parcel, express or freight shipping as well as collection.
