The Miniature Stepper Motor MR11xx series was developed primarily as an indicator drive for dashboard instrumentation and other indicator equipment. The motor can operate directly from a numerical driving signal to move and position a pointer to visualize any parameter required. The miniature stepper motor consists of a motor and gear train with a reduction ratio of 1/180. It is produced with the advanced technologies in precision parts and micro drive of MCR MOTOR. These technologies assure a high quality product. The motor is simple in construction without concessions to stability or longevity.
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, MR11xx series motor has high reliability during the temperature range of -40°C－105°C. So malfunction caused by weld defect or open circuit will not appear.
Positioning assembly of the gear makes the motor stop vibrating when the pointer returns to zero.
