1. rps 920 0044D STM24 Hardware Manual 10 7 2011 Drive Motor Heating Step motors convert electrical power from the driver into mechanical power to move a load Because step motors are not perfectly efficient some of the electrical power turns into heat on its way through the motor This heating is not so much dependent on the load being driven but rather the motor speed and power supply voltage There are certain combinations of speed and voltage at which a motor cannot be continuously operated without damage We have characterized the STM24 in our lab and provided curves showing the maximum duty cycle versus speed for commonly used power supply voltages Please refer to these curves when planning your application Please also keep in mind that a step motor typically reaches maximum temperature after 30 to 45 minutes of operation If you run the motor for one minute then let it sit idle for one minute that is a 50 duty cycle Five minutes on and five minutes off is also 50 duty However one hour on and one hour off has the effect of 100 duty because during the first hour the motor will reach full and possibly excessive temperature The actual temperature of the motor depends on how much heat is conducted convected or radiated out of it Our measurements were made in a 40 C 104 F environment with the motor mounted to an aluminum plate sized to provide a surface area consistent with the motor power dissipation Your resul2. 23 140 2 01171 22202006 re eee eee E ee meen eee eee eee ee 25 2010 _ 28 018 000 29 E 22 20 30 20020038 m 31 22200222 Ue 32 920 0044D STM24 Hardware Manual 10 7 2011 Introduction Thank you for selecting the Applied Motion Products STM24 Drive Motor We hope our dedication to performance quality and economy will make your motion control project successful If there s anything we can do to improve our prod ucts or help you use them better please call or fax We d like to hear from you Our phone number is 800 525 1609 you can reach us by fax at 831 761 6544 You can also email support applied motion com Features Programmable micro stepping digital step Drive Motor in an integrated package Operates from a 12 to 70 volt DC power supply Operates in velocity or position mode Mid band anti resonance Accepts analog signals digital signals and streaming serial commands Step input signal smoothing Communication options RS 232 RS 422 485 CANopen Optional encoder feedback Delivers up to 340 oz in holding torque SF amp four optically isolated 5 to 24 volt digital I O points each can be configured as an input an output C three optically isolated 5 to 24
