M-S Motor (X25.xxx)

The Miniature Stepper Motor X25.xxx was primarily developed as an indicator drive for dashboard instrumentation and other indicator equipment. The X25.xxx can operate directly from a digital driving signal to move and position a pointer to visualize any parameter required.

Its inherent properties of torque, low current consumption, small size, light weight, etc... extend its use also to other applications.

 MS-Motor

The motor principle is based on a three poles synchronous motor designed and patented for a bidirectional watch stepper motor. Its simple structure with few components and its efficiency allowed a highly reliable and cost effective design. The miniature stepper motor consists of a motor and gear train with a reduction ratio of 1/180.

Main Features
  • 1/3° resolution per step
  • Low current consumption
  • Small dimensions: Ø 30 X 9 mm
  • High speed: up to 600°/s
  • Large static torque
  • Can be directly driven by a µ-controller
  • Large temperature range: -40°C / +105°C
  • Fully qualified for automotive applications

Application Notes: Please contact the customer service in order to get the application notes.

M-S Driver

M-S Dual Driver (X12.014)

M-S Quad Driver (X12.017)

Two/Four motors can be driven with these Driver IC's. This IC is a monolithic CMOS devices intended to be used as an interface circuit to ease the use of the Miniature Stepper Motor M-S X25.xxx. This Driver IC has been specifically designed for applications in the car dashboard.

The driver circuit converts a pulse train f(scx) into a current level sequence sent to the motor coils. This sequence is used to produce the microstepping movement of the motor. A microstep corresponds to an angular rotation of 1/12°. of the pointer. The microstepping allows for smooth and appealing movement of a pointer.
