1PC N20/N30/N50 Metall Getriebe Getriebe Motor DC 3V-12V 4rpm-380rpm Langsam Geschwindigkeit Hohe Drehmoment Motor mit Selbst-locking DIY Roboter Auto

Tips:  The applicable voltage of each motor is 3V-12V. In this voltage range, the higher the voltage, the higher the speed, the greater the torque. Model (A )has the slowest speed and the largest torque. Model (F) has the fastest speed and the smallest torque. 050 Gear Motor  Reduction ration:A(1030:1), B(603:1), C(236:1),D(118:1), E( 79:1 ), G( 42:1 ), H(21:1) Voltage range: 3V-12V Weight : 24g Speed error:±10% Rotating speed: A＜B＜C＜D＜E D>E>>G>H Shaft length: 8mm Shaft diameter:3mm(2.5mm D Shaft) ========================================================================= N30 motor  Reduction ration: Model A(1030:1),    Model B(603:1),   Model C(302:1),    Model D(236:1),   Model E(118:1),     Model G(42:1) Voltage range: DC  3V-12V Weight :13g Speed error:±10% Rotating speed: A＜B＜C＜D＜E＜G Torque: A>B>C>D>E>G Shaft length: 7.5mm Shaft diameter:3mm(2.5mm D Shaft) ==================================================================== N20 Gear Motor  Reduction ration: Model A(1030:1),    Model B(603:1),   Model C(302:1),  Model D(236:1),  Model E(118:1),  Model G(42:1) Voltage range: DC  3V-12V Weight :13g Speed error:±10% Rotating speed: A＜B＜C＜D D>E>G Shaft length: 7.5mm Shaft diameter:3mm(2.5mm D Shaft) ==================================================================== Gear Motor x 1pc
