Stepper motor resolver

hollow-shaftrobust

Resolver (angle encoder) are used wherever the angular position of a mechanical element is required. They strengthen their position in many applications of the industry as a robust and cost-effective solution. It is less sensitive to eccentricity and magnetic stray fields. The robust design allows to use resolvers also in liquid nitrogen (-197° C), in a high vacuum (up to +200° C) and in highly radioactive environment. • 2 Resolver sizes for the VSS motors of size 25 to 126 • Insensitive to magnetic stray fields • Nuclear requirements > 10° Rad • Temperature range from - 60 to 250 °C • Frequency 6 to 12 kHz • Primary impedance 94 or 115 9 • Secundary impedance 51 or 190 $2 • Transformation ration 0.5 • Inertia of rotor 1 or 20 g/cm2 • Weight: 35 or 95 g
