QSH4218 Manual (V1.11 / Feb 8th, 2006) 3 1 Features These two phase hybrid stepper motors are optimized for microstepping and give a good fit to the TRINAMIC family of motor controllers and drivers. They are also used in the 57mm PANdrive family. Main characteristics: • NEMA 17 mounting configuration • flange max. 42.2mm * 42.2mm • 5.0mm axis diameter, 20mm axis length • step angle: 1.

QSH4218 Manual (V1.11 / Feb 8th, 2006) 5 3 Mechanical Dimensions 3.1 Leadwire Configuration The leadwires come in a number of different color coding schemes. Please determine which scheme fits for your motor first. Cable type is AWG 24.
QSH4218 Manual (V1.11 / Feb 8th, 2006) 6 4 Torque figures The torque figures detail motor torque characteristics for fullstep operation in order to allow simple comparison. The motors were positioned on rubber. The diagrams are based on discrete measurement points of pull-out torque (torque needed to stop rotating motor). For fullstep operation there are always a number of resonance points (with less torque) which are not depicted. These will be minimized by microstep operation in most applications. 4.

QSH4218 Manual (V1.11 / Feb 8th, 2006) 8 5 Considerations for Operation The following chapters try to help you to correctly set the key operation parameters in order to get a stable system. 5.1 Choosing the best fitting Motor for an Application For an optimum solution it is important to fit the motor to the application and to choose the best mode of operation. The key parameters are desired motor torque and velocity.
QSH4218 Manual (V1.11 / Feb 8th, 2006) 9 Hints: Q: How to choose the optimum current setting? A1: Generally, you choose the motor in order to give the desired performance at nominal current. For short time operation, you might want to increase the motor current to get a higher torque than specified for the motor. In a hot environment, you might want to work with a reduced motor current in order to reduce motor self heating.
QSH4218 Manual (V1.11 / Feb 8th, 2006) 10 Hints: Q: How to determine if the given driver voltage is sufficient? A1: Just listen to the motor at different velocities. Does the “sound” of the motor get raucous or harsh when exceeding some velocity? Then the motor gets into a resonance area. The reason is, that the motor back-EMF voltage reaches the supply voltage. Thus, the driver can not bring the full current into the motor any more.
