SPECIFICATIONS
TRADELINE ® Models
TRADELINE models (M6284D1000, M6294D1008) are
selected and packaged to provide ease of stocking, ease of
handling, and maximum replacement value. TRADELINE
model specifications are the same as those of standard
models, unless specified otherwise. TRADELINE models
have auxiliary switch cams.

a
Breakaway torque is the maximum torque available to
overcome occasional large loads such as a seized damper
or valve.
Motor must not be used continuously at this rating.
b
Stalling of 2 or 4 minute motor may damage drive shaft.
Dead Weight Load on Shaft:
Power or Auxiliary End: 200 lb (90.8 kg) maximum.
Maximum Combined Load: 300 lb (136 kg).
Dimensions:
See Fig. 1.
Ambient Temperature Ratings:
Maximum: 150°F (66°C) at 25% duty cycle.
Minimum: Minus 40°F (-40°C).
Crankshaft: 3/8 in. (9.5 mm) square.
M6284, M6294 have dual-ended shaft.

Feedback Potentiometer:
115 ohms. TRADELINE® models are 600 ohms linear,
configurable for W902 Control or for slaving Series 90 motor.
Controller Type:
3-wire floating (Series 60)—drive open, hold, drive closed.
Internal, electrically isolated feedback potentiometer
provides indication of motor position.
Stroke:
Fixed stroke models available with 90° or 160° stroke. Other
models available with stroke field adjustable from 90° to 160°.
Start position of shaft changes with adjustment of stroke.
(Midpoint of stroke remains fixed as stroke is adjusted. Stroke
is adjusted by using cams located in wiring compartment.)
