Times superior 28 series reduction stepper motor, step distance 1.8°, current 0.8A, reduction ratio optional, this motor is small in size and large in output.

There are a variety of body lengths, which can be matched with different speed ratio reducers, mainly used in stage lighting marking machines, instruments, medical machinery, automation devices and other occasions that require small volume and high torque.

The motor parameters and reducer parameters are as follows:

So how to choose the motor and reducer. To achieve the output torque you need?

First of all, we need to understand

The output torque of the motor + reducer = motor torque * reduction ratio * output efficiency of the reducer < rated torque that the reducer can withstand

FOR EXAMPLE, THE 34MM STEPPER MOTOR WITH A LENGTH OF THE FUSELAGE IS EQUIPPED WITH A 19-SPEED RATIO REDUCER, AND THE OUTPUT TORQUE = 0.1NM * 19 * 90% = 1.7Nm < 1.9NM

Therefore, 1.7N.m can be output.

And so on, we can achieve other gear ratios with torque. The result is the final output torque.

This total motor due to the current is very small, with the general driver will heat up relatively large, so we recommend the use of our company's ZD-2HD318 driver, stable performance, small heating, drive 0-1.8A current adjustable.

ZD-2HD318 high-performance two-phase stepper motor driver has high integration and high reliability; The interface adopts high-speed optocoupler isolation; Maximum output current 1.8A, input voltage: DC 32V (peak); Short circuit, overcurrent, overtemperature protection function; Internal 0-10K pulses per second for simple control; High subdivision, maximum support 128 subdivision settings.

Key Features:

Full step, 2, 4, 8, 16, 32, 64, 128 subdivision adjustable.

Short circuit, overcurrent, overtemperature protection function automatic protection.

Automatic half-flow lock, reduce standby heating.

Support offline, enable, lock and other functions.
