Max - Relsig – 22 Nov 2017
Excellent economical motor for cost effective use to achieve high torque while requiring lower speed. This product was used by my team and I for robotic arm. good size and lightweight. Shipping came as described and fast. Output was as desired and have great driving strength & torque.
Packaging was neat and well cushioned
Not recommended for use with high speed needs, consider 19:1 or 5:1 ratios if higher speed needs are required. Also, output shaft would need an efficient method to hold or couple because the material is passable grade aluminium.
All in all still a very good all inclusive motor with gearbox and ready attached wires.
