U.S. TSUBAKI DISCO
STANDARD MODEL CHARACTERISTICS K Series DISCO
Output Shaft Torque vs. Output Shaft Speed (Basic Type)
Specifications
in. -lbs.
DISCO infinitely variable speed drive K series
Characteristics
Constant torque and constant horsepower interim characteristics
Output shaft torque
At low speed, twice the high-speed torque
Variable speed ratio
6 to 1 (Note: for 15 h.p. and above — 5 to 1)
200 to 1,200 rpm with 60 Hz - 4P Motor directly connected (Note: 240 to 1200 rpm for 15 h.p. and above)
Output shaft speed
Use for applications where load torque is constant regardless of speed, and select by calculating the load torque at maximum speed
Use and selection points
Basic (without speed reducer)
Available Type
With helical gear speed reducer (2.5:1 through 45:1)
NOTE: DISCO selection covered on pages D-79 and D-80.
