The MR1100 Series Stepper Motor was developed primarily as an Indicator Drive for Dashboard Instrumentation, but ideal for other Indicator Equipment. The MR1100 Series Stepper Motor can operate directly from a numerical driving signal to move and position a pointer to visualize any parameter required. The MR1100 Series Stepper Motor consists of a motor and gear train with a reduction ratio of 1/180. It is produced with the most advanced technologies in precision parts and micro drive assembly. These technologies assure a high quality finished product. Full steps can be carried out up to 600Hz resulting in a 600°/s angular speed. Such characteristics allow a large dynamic range for indicator applications. As a result of advanced coil welding technology and automatic dust-free assembly production, the MR1100 Series Stepper Motor offers unsurpassed reliability and a wide operating temperature range of -38°F - 221°F. All MR1100 Series Stepper Motor internal coils are terminated by copper to copper arc welding for the absolute best connection. This prevents malfunctions found in soldered connections that end up in open circuits from defective cold solder joints. The MR1100 Series Stepper Motors utilize precision gear assembly to prevent motor vibration when the pointer returns to the zero position.
