M818T‑040, which appears to be a servo motor—most likely a DC servo motor—commonly used in precision industrial applications.

• The M818T‑040 is a DC servo motor manufactured by Sanyo Denki, often used in spark wire-cut EDM (Electrical Discharge Machining) machines. It may also function as a tachometer generator in certain configurations 

• The motor is part of the M818T series, related to models like M818T‑031, M818T‑032, and M818T‑400 RicoCNCRicoCNCRico CNC.

• One supplier mentions a broader industrial context: the M818T‑040 as an AC servo motor, rated at:

  • 22 kW

  • 48 V DC

  • Speed: 2,000 RPM

  • Efficiency: IE4

  • Though this may refer to a possibly mismatched listing—some sources list it as AC, others as DC 

While explicit specs for the M818T‑040 are scarce, we can infer reasonable estimates based on its sibling models:
