Torqmotor™ TE Series features
include:
• Roller vanes to reduce friction and internal
leakage and to maintain effi ciency.
• Zero leak commutation valve provides
greater, more consistent volumetric ef-
fi ciency.
• Wheel mount version available.
• More starting torque than competitive mo-
tors in applications where the shaft is side
loaded. (Competitive brands require more
pressure to start the motor.)
• A needle-roller mounted coupling shaft
and steel-caged thrust bearing which can
withstand 1000-pound thrust loads.
• Side load capacity is 1600 lbs. (727.3 kg)
maximum at center of output shaft.
• A unique high-pressure shaft seal that
eliminates the need for case drains, check
valves and extra plumbing.
• Up to 17 horsepower output.
• Greater durability due to superior lubrica-
tion and minimum drive spline wear.
• Patented 60-40 spline member arrange-
ment transmits more torque with less weight.
Torqmotor™ Design Features
Torqmotor™ TB/TC Series features
include:
• The roller vane rotor set design offers
a low-friction, wear compensation which
maximizes the useful performance life of the
motor.
• Zero leak commutation valve provides
greater, more consistent volumetric ef-
fi ciency.
• Design fl exibility - TB offers the widest
selection of shaft options, displacements
and mounting fl anges in the industry.
• Patented 60-40 spline member arrange-
ment transmits more torque with less weight.
• Full fl ow lubrication maximizes cooling
and may provide up to 50% longer life than
motors not having this feature.
• Higher pressure rating provide greater
torque than competitive brands.
• Full interchangeability with other motors
which are designed according to industry
standards.
• Compatible with most hydraulic systems
with regard to pressure, torque and speed.
• A unique high-pressure shaft seal that
eliminates the need for case drains.
• Up to 13 horsepower output.
