75:1 SANYO Micro Gearbox Motor



This Sanyo NA1S 75.7:1 reduction gear motor is only 29mm (1.14") long (overall), 10mm (0.39") thick, and 12mm (0.47") wide and it's made with metal gears. These gear units are quality built!

These 8.2 gram (0.29oz) motors are rated for 246 RPM, drawing 120mA @ 5V, producing 800gf*cm torque (11 in*oz) and stalling out at 580mA. The 3mm diameter output shaft mates pretty well with any 1/8" hole output device.

Disclaimer: These motors are to be used for Hobby use only and should not be used in applications where motor failure could cause bodily harm or loss of life.

Additional gear box specification see NA1S PDF File (100K)

Includes 2 Metric Screws for Faceplate.

This metric 1.7 (dia) x 0.35 (mm/thd) x 4mm long bolt exactly matches the unique thread on the two bolt-holes on the faceplates of the GM12 series of gear motors.
These screws make it easier to precisely mount your motor to your project!

Servo Motors

We carry a wide range of servo motors from the "feather" HS-50 to the powerful HSR-5995TG Digital Titanium Robot Servo. For information on how to use these motors, see our article: Using Servomotors with the PIC Microcontroller. We also carry a Servo Motor Controller boards for controlling servos either manually (via toggle switches) or PC windows (98/XP).

SMC-04 ServoMotor Controller
Images manufacturers three servo motor controller boards. The SMC-04, SMC-05 and the SMC-08. The SMC-04 is shown to the left. Click on picture to view other servo motor controller boards available.

Images Company’s SMC-04 and SMC-04A Servomotor Controllers allow Manual & PC control of four hobby servo motors (Hitec/Futaba). Servomotors may be controlled manually, via on-board switches, or by a Windows program through a serial communication port (RS232) on a Windows 98/XP PC.
Universal three position headers make it easy to connect servo motors--just plug them into the board.

Manual Control: Each servo motor is controlled using a three-position switch on the servo motor board. Each switch position controls the servo motor in the following manner: UP = clockwise, DOWN = counterclockwise, and stop is the CENTER off position.

PC Control: Windows 98 and Windows XP programs, (price includes CD Rom programs) see screen image, use the PC serial port to communicate to the servo motor board. Each program incorporates an adjustable servo motor speed control. Each servo motor is controlled by an individual slider. In the script writing mode every servo motor movement is automatically recorded and written into the onscreen script area. The onscreen script may be saved, loaded, played, and looped. Updated Windows PC programs are always available for download here.
