Instrument stepper motors The instrument stepper motors are high quality permanent magnet types providing a 7.5 degree step angle The motors may be specified factory fitted with a gearhead where increased torque and resolution are required at reduced operating speed. The programme has gained a world-wide reputation for high reliability and is widely used in industrial control and instrumentation drives. The miniature 1415 series, incorporates a low backlash precision gearhead to provide outstanding torque and resolution for a unit of such compact dimensions. A comprehensive programme of drives, power supplies and controllers have been developed to match the motors characteristics to enable single or multi-axis systems to be readily constructed. ID series motors are either provided with leads ID series stepper motor dimensions ( Form 1 A ) or solder terminals ( Forms 1B & 1C) as shown below: L7 L1 L2 D4 L5 T1 D2 D1 T2 L4 D3 L6 L8 L3 T1 Form 1 Form 1A Form 1B Form 1C motor type form dimensions mm D1 D2 D3 D4 L1 L2 L3 L4 L5 L6 L7 L8 T1 T2 9904 112 series 1 A 35 2 10 3.2 21.5 8.8 50 42 1.2 0.8 2.2 175 N/A N/A 9904 112 31001 1 A 51 3 10 3.5 25 8.2 70.5 60.2 1.5 1.0 3 175 N/A N/A 9904 112 31101 9904 112 31004 1 B 51 3 10 3.5 25 8.2 70.5 60.2 1.5 1.0 3 N/A 38.5 18.3 9904 112 31104 9904 112 35 series 1 C 56.3 4 12 4.4 33.5 16 76.5 66 1.5 1.5 3.8 N/A 37.1 20 specification motor type step holding rotor resistance current inductance number mass angle torque inertia per phase per phase per phase of leads or 2 degrees Ncm Kgcm ohms amps mH terminals gms 9904 112 32001 7.5 1.0 0.0026 120 0.1 160 6 80 9904 112 32101 7.5 1.0 0.0026 21 0.22 30 6 80 9904 112 31004 7.5 2.8 0.011 65 0.175 100 6 terminals 170 9904 112 31001 7.5 3.0 0.011 62 0.190 160 8 200 9904 112 31104 7.5 3.2 0.011 11 0.4 16 6 terminals 170 9904 112 31101 7.5 3.4 0.011 17 ..0.325 45 8 200 9904 112 31206 ** 7.5 5.5 0.011 7 0.50 18 4 170 9904 112 35014 7.5 8.5 0.045 47 0.24 400 6 terminals 300 9904 112 35114 7.5 8.5 0.045 7.7 0.60 65 6 terminals 300 Precision Geared stepper motors 1415 - 41:1 ** 0.366 10 0.00045 12.5 0.25 5.5 4 47 1415 - 76:1 ** 0.197 10 0.00045 12.5 0.25 5.5 4 50 1415 -141:1 ** 0.106 10 0.00045 12.5 0.25 5.5 4 50 note** The above motors are, in general, 4 phase units suitable for use with uni-polar or bi-polar drive circuits.
