BAUMULLER 21-30/45-30-00 1 Resolver Feedback Component

Technical Specifications

Model: 21-30/45-30-00 1 Brand: BAUMULLER (Baumüller, Germany) Product Type: Servo Motor Resolver Feedback Sensor Structure: Wound rotary transformer type Mounting: Shaft mounted, fitted to BAUMULLER servo motor rotor Operating temperature: -20℃ ~ +80℃ Storage temperature: -25℃ ~ +85℃ Relative humidity: 5%~95%, non-condensing Protection: IP54 (when assembled inside motor housing) Weight: 0.31kg

System compatibility

21-30/45-30-00 1 is a resolver for BAUMULLER servo motors, compatible with b maXX series servo drives. It is widely used in printing, metal forming, plastic extrusion and textile machinery for position closed-loop control overhaul.

Function

21-30/45-30-00 1 rotary resolver mounted on servo motor rotor. It detects rotor angular position and rotational speed through electromagnetic induction principle, sends analog feedback signals to servo drive. The drive uses these signals to calculate motor commutation and precise positioning. It replaces damaged resolver during motor maintenance.

Installation

Cut off all power of servo system before disassembly. Remove motor rear housing, align resolver to motor rotor shaft, fix mounting screws carefully. Reconnect resolver signal cable to drive control board. Perform position offset calibration, test motor closed-loop operation before putting into production.

Interface

Resolver excitation and signal output wires, internal mounting flange for 21-30/45-30-00 1 BAUMULLER resolver.

Feature

BAUMULLER original resolver, high shock and vibration resistance, no optical components, suitable for dusty and high-temperature machine environment, industrial anti-interference design. This legacy spare part used for old BAUMULLER servo motor position feedback maintenance and replacement.

Diagnostic

Drive resolver fault alarm: check resolver wiring and shaft alignment for 21-30/45-30-00 1. Motor positioning inaccuracy: inspect winding integrity and signal amplitude. Intermittent speed fluctuation: verify cable shielding and connector contact.

Product Brief

21-30/45-30-00 1 is German BAUMULLER rotary resolver for servo motor. It provides rotor position and speed feedback for closed-loop motion control, classic spare part for legacy BAUMULLER servo motor overhaul.
