DKM 9RD-40 Reversible Motor 40W, 90 mm Frame

DKM 9RD-40 Reversible Motor 40W, 90 mm Frame

40 W single-phase reversible motor with 90 mm square frame, designed for frequent forward/reverse switching, with built-in friction brake; D-cut, key or gear-type (pinion) output shaft for DKM gearboxes.

Key features

  • Designed for applications that require frequent changes of direction
  • Capacitor-run single-phase motor with higher starting torque than an induction motor
  • Built-in simple friction brake (approx. 10% of motor output) reduces overrun and improves instant reversing
  • Rated time 30 minutes; longer operation possible with intermittent duty
  • Gear-type shaft models combine with DKM gearboxes
