Product Description
Nema 17 42 mm*42 mm Stepper Motor With Gearbox Wholesale 12 V 30 Ohms 0.4 A
The stepper motors move in precisely repeatable steps, hence they are the motors of choice for the machines requiring precise position control. The NEMA 23 2.5 kg.cm Hybrid Stepper Motor provides excellent response to starting, stopping, and reversing pulses from the stepper motor driver.
A stepper motor, also known as step motor or stepping motor, is a brushless DC electric motor that divides a full rotation into a number of equal steps. The motor’s position can be commanded to move and hold at one of these steps without any position sensor for feedback.A hybrid stepper motor is a combination of the variable reluctance and permanent magnet type motors.
