Product Short Description

Product Name: MKD Series Synchronous Servo Motor (No Holding Brake)

Product Description: Compact permanent magnet synchronous servo motor without holding brake, belongs to Rexroth MKD series, optimized for horizontal axis applications.

Description

Technical Specifications: Motor size 025, B-length stator, winding code 144, resolver feedback, 54mm flange size, 40mm centering diameter, continuous standstill torque 0.9Nm, keyed shaft per DIN 6885-1, IP65 protection, no holding brake.

Functional Features: Low inertia rotor, high acceleration performance, resolver position feedback, compact volume, lightweight design, cost-effective for non-vertical axis applications.

Application Scenarios: Horizontal axis automation equipment, sorting machinery, small handling robots, testing and inspection equipment, light assembly lines.

Performance Parameters: Maximum speed up to 9000rpm, rotor inertia 2.1×10⁻⁴ kgm², fast start-stop response, low torque ripple.

Material Composition: Aluminum alloy heat dissipation housing, high-performance permanent magnet, keyed steel shaft with shaft seal ring, insulated copper winding.

Structural Features: Flange mounting structure, keyed output shaft, resolver feedback module at rear, natural convection cooling design.

Working Principle: Permanent magnet synchronous motor, resolver feeds back rotor position signal, servo drive outputs three-phase current to control motor torque and speed accurately.

Installation Requirements: Flange fixed installation, align load and motor shaft concentricity, ensure proper wiring of resolver cable, comply with EMC wiring specifications.

Notes for Use: This model has no built-in holding brake; add external brake for vertical load applications; avoid shaft radial overload; do not use in applications requiring power-off holding.
