Nmea34 Stepper motor heating problem

Hi all,
We are using a Nema 34 stepper motor driving it using Leadshine M542 driver and arduino UNO.
24 V voltage and 4.2 A peak current being given.
Our motor lifts a metal frame for about a minute (it has to rotate about 1minute) and needs to hold it the 4-5 hours at fixed position.
Now it draws the same current when its running( lifting) and while its holding which makes it a continuously current drawing motor and becomes heated extremely as time goes.
Kindly suggest me a solution.

It is normal for a stepper motor to be very hot - uncomfortable to touch. Ensure the current limit setting in your stepper driver matches your motor.

If the motor is bolted to a metal support that will help to dissipate the heat.

A simple DC motor driving through a non-reversible worm gear is likely to be the most efficient way to hold a load for long periods as no power is needed to hold position.

Hi,
Welcome to the forum.

What is the part number of your stepper and can you post links to its data/spec sheet please?

Thanks.. Tom.. :slight_smile:
