Kollmorgen TTR-5301-137-A
Product Overview:
The TTR-5301-137-A is a legacy Kollmorgen Industrial Drives (KID) product — typically a brushless servo motor or a matched resolver/feedback sub-assembly originally supplied with Goldline-era motors. Many TTR-prefixed parts are replacement rotors, stators, or complete motors with built-in resolver feedback for B/M-series.
Detailed content
Typical Characteristics (when TTR denotes a complete motor):
-
Type: 2-pole or multi-pole permanent-magnet brushless servo motor
-
Feedback: Integral brushless resolver (BRX type), excitation 2–10 kHz, transformation ratio ~0.5
-
Mounting: NEMA or metric flange per original B/M-frame
-
Winding: 115/230 VAC class
-
Thermostat: Included
When TTR denotes a resolver/feedback unit:
-
Construction: Stator/rotor resolver pair, mounted on motor rear extension
-
Accuracy: ±10 arc-min typical (single-speed); multi-speed versions available
-
Operating Temp: -40°C to +155°C
-
Sealing: Epoxy-potted, vibration-resistant
Application Notes:
-
Match resolver transformation ratio and excitation frequency to drive capability
-
Verify shaft extension length and connector pinout before installation
-
Often used as spare/replacement part in existing installed base machinery
