💕The reducer’s maximum instantaneous load is 6.0kg.cm.
💕For reliable operation, we recommend keeping the normal operating torque below 4.0kg.cm.
💕The speed is calculated using the following formula: Speed (rpm) = Step Angle × Frequency × 60 ÷ 360.
💕The high torque stepper motor’s technical specifications are for guidance，we offer custom solutions upon request.

FAQ for stepper gear motor
Q：What is a Stepper Motor?
A:A stepper gear motor combines a stepper motor with a gearbox.It’s a brushless DC motor that moves in small, precise steps. You can set it to any position without a sensor. The gearbox then lets it drive heavier loads with slow, controlled movements.
