While the 1970's ushered in Nutron's DVT hydraulic servomotor, the 1980's marked a breakthrough in design for the NEW Nutron BV series motors. In 1988 Nutron Motors joined the Ifield Technology Group, which immediately dedicated themselves to the establishment of high levels of product development and quality control. Many satisfied OEM's and End Users are benefiting from this dedication.
During the 1990's a full range of hydro-electronic controls have been incorporated into the BV series servomotor. Uniquely designed, Nutron motors suit a wide variety of applications. They are readily available through a network of national and international distributors.

Unique Design : Spherical Pistons at the heart of the Nutron Motor
The uniquely designed Nutron fluid motor is based on the principle of free, chrome alloy spherical pistons rolling upon multi-wave cams. Torque is produced by the reaction of these spherical pistons against the slope of the cam track. This unique multi piston configuration provides quiet, shock-free, porting with near zero leakage.
Nutrons patented (U.S. Patent No. 3662551) pressure compensation system monitors the delta pressure on the A & B ports. The internal case will see the return port pressure, so that the torque is produced by the net pressure difference acting on the drive pistons which transmits the torque. This compensation system enables the Nutron fluid motor to maintain a constant speed regardless of load, even below 1 rpm. In effect, the motor "locks on" to any pressure compensated flow control valve, in the return line and hence modulates its own torque output to exactly hold the speed set by that valve.
