Kollmorgen TT-29370-3120-B6

Product Name:​ TT Series Permanent Magnet DC Servo Motor (Legacy/Obsolete Line)
Product Introduction:​ The TT series is a legacy line of Kollmorgen brushed or brushless DC servo motors, widely used in older high-precision applications. The numbering “29370-3120-B6” refers to the specific frame, stack, winding, and commutation/feedback configuration.

Detailed content

Identification:
  • TT:​ TT Series (classic Kollmorgen frameless or housed servos).
  • 29370:​ Likely frame size / stack length code.
  • 3120:​ Winding / voltage constant code.
  • B6:​ Commutation/tachometer/feedback option (e.g., B = specific mount or brake, 6 = resolver or encoder type).
Typical Specifications (Legacy Context):
  • Type:​ Often rare-earth magnet DC servo (brushed) or early BLDC.
  • Torque:​ Varies widely; TT series covers low to mid torque ranges (e.g., 1-20 Nm continuous depending on size).
  • Speed:​ Typically 1500-3000 rpm base.
  • Commutation:​ May include built-in tachogenerators, Hall sensors, or resolvers.
  • Mounting:​ Flange mount, NEMA or metric dimensions.
Material:
  • Magnets:​ Samarium Cobalt (SmCo) or Alnico in older units; later units Neodymium.
  • Housing:​ Cast aluminum or steel.
  • Brushes:​ Carbon (if DC brushed version).
Applications:​ Retrofit of legacy machine tools, aerospace test stands, medical imaging (older CT gantries), semiconductor steppers (obsolete).
Operating Considerations:Obsolete product; replacement typically requires upgrading to AKM or 2G series with new drives. Brushed versions require brush inspection/replacement. Insulation may degrade in units >20 years old. Feedback devices (tachometers) are susceptible to wear.
Installation:​ If replacing like-for-like, note shaft keyway, connector pinout (often MS connectors or terminal blocks), and grounding scheme which differs from modern AKM motors.
