Product Description:

The 103F7852-7041 is a moderate size stepping motor from Sanyo Denki which is able to deliver precise movement with a high degree of accuracy and good torque capacity. It is suitable for medium load industrial automation applications that require precise and controlled motion.

The 103F7852-7041 Stepping Motor is a lighter motor with a weight of 1.2 kg which may be preferred in certain applications to reduce overall system weight. Each phase of this module is consuming 1.4 amperes. The type of circuit used to drive the motor is Sanyo constant current circuit which ensures that the motor receives a steady current for reliable operation that improves performance and reduces power fluctuations. The effective tapping depth of the module is 0.13 inches which refers to how deep the screws can be inserted into the motor’s housing for secure mounting and ensures the motor is properly fixed in place and avoids loose connections. The inductance of the windings in each phase of this module is 0.8 mH/phase which impacts how the motor responds to changes in current that affects its efficiency and speed characteristics.

The StepSyn stepping motor shaft can bear along a radial direction of 360 N which affects the bearings and can influence the life span and performance of the motor. Exceeding the load from this value could damage the motor. This stepping motor has a length of 55mm from end to end which affects its overall size and form factor. The Instantaneous Max Torque is 20 Nm which represents the motor’s ability to handle short term overloads or acceleration. Along the length of the shaft it can bear a maximum load of 400 N.
