Product Description:
The MKD071B-035-GG0-KN is a servo motor built by Bosch Rexroth Indramat as part of the MKD Synchronous Motors series. Designed for integration into closed-loop drive systems, the motor converts controlled electrical energy into mechanical rotation for positioning and speed-control tasks in automated machinery. Its compact 071 frame size and B length allow it to fit medium-power axes on packaging lines, handling stations, and machine tools, where stable response and repeatable motion are required during frequent starts, stops, and direction changes. That role also suits servo applications that depend on accurate speed regulation over long production cycles.
The motor delivers a continuous standstill torque of 8.0 Nm, supplying steady holding force when the axis is energized but motionless. A front flange diameter of 115 mm aligns with industry-standard mounting patterns, while the 95 mm centering seat ensures concentric installation and limits radial runout during coupling. Electrical and feedback leads exit on Side B, which can simplify cable routing in compact machine layouts and reduce crossover near adjacent components. All power terminals are grouped in a connection box, which keeps the main wiring organized and separate from the feedback connection. The 071 frame, combined with the 035 winding code, balances thermal loading with current demand, and the B length provides additional active copper for extended duty.
Motion feedback is supplied through resolver feedback, and the corresponding electronics interpret the sinusoidal signals as relative position detection, so the connected drive performs a homing routine at startup. Because the feedback is relative rather than absolute, the axis reference is established after the machine is powered. The shaft is a plain shaft, allowing direct coupling through clamp hubs or keyed bushings, and a factory-installed shaft seal helps keep lubricant and contaminants away from the stator cavity. The unit is supplied without a holding brake, so any required load holding during power loss must be handled by external mechanical means. Winding code 035 identifies the electrical winding matched to moderate-voltage inverters and the expected motor parameters for the associated drive.
Frequently Asked Questions about MKD071B-035-GG0-KN:
Q: What encoder type does the MKD071B-035-GG0-KN motor use for position feedback?
A: The MKD071B-035-GG0-KN features resolver feedback (RSF) for position detection, providing relative positional data.
Q: Does the MKD071B-035-GG0-KN motor include a holding brake?
A: This motor operates without a holding brake, which means it does not provide passive resistance to motion when powered off.
Q: What is the continuous torque at standstill for the MKD071B-035-GG0-KN?
A: The motor can deliver a continuous torque of 8.0 Nm at standstill, allowing it to maintain loads without overheating during non-rotational operation.
Q: What type of shaft design is present on the MKD071B-035-GG0-KN motor?
A: The shaft design is a plain shaft, which enables direct coupling to loads without specialized shaft interfaces.
Q: Where is the connection box located on the MKD071B-035-GG0-KN?
A: The electrical connection is made through a connection box positioned at Side B of the motor.
