1 PRECISION MOTOR- POTENTIOMETER SAKAE -Potentiometer Series are a kind of servo units consisting of a precision potentiometer of our manufacture combined with a reduction gear mechanism and a coreless D.C. motor. Their housing is compact and strong based on our own design and there are versatile items in this series among which you can choose ones to be suitably convenient for the design of your own applications. Precise mechanism, high reliability, extreme stability, high power for input as well as output and long life expectancy can satisfy your various requirements. SAKAE Servo Amplifier and D.C. Power Supply in accordance with performances of motor potentiometers offer many stable electrical performances and have a compact and strong housing case as well as terminal block to make easy connections. Circuit construction is easily made with these devices and motor potentiometers. THE NOMENCLATURE OF SAKAE MOTOR-POTENTIOMETER SERIES S MPH B 7 5HP- 5 kω.5 Special Specifications S means the potentiometer with special mechanical specifications not applicable to our standard. MPH means motor-potentiometer. Diameter means approximate outer diameter of the housing in metric system. The 4 standard diameters are available: mm, mm, 5mm and 46mm.

8 Suggestions and cautions on the use of motor-potentiometers ) ) Our standard input voltage for the motor is 6 V.D.C. and other input voltages such as V.D.C., 4 V.D.C., and etc. are also available on request. As the rated voltage of motor is usually lower than that of potentiometer, when checking the insulation resistance and dielectric strength of the motorpotentiometer, please do not load with over V on the unit. The rotating direction of the shaft of potentiometer which drives from motor is depending on a reduction gear ratio of the reduction gear to be incorporated. ) 4) When using, please confirm the rotating direction to avoid any inconveniences. We can supply our motor-potentiometers with slipping torque of up to approx..n m (kgf cm) by adjusting at our side to your request in advance. Our standard slipping torque is 5mN m (5gf cm), unless otherwise specified. But the load to the shaft is to be adjusted by below / of slipping torque value. When rotating the motor through the amplifier, the motor-speed does not always become a linear function.
