The problems related to the stator winding of spindle motors brought to our workshop for repair and maintenance purposes are resolved in our dedicated winding facility. In our well-established winding workshop, we are capable of successfully and professionally handling the winding (rewinding) of various types of electric motors, including servo motors, spindle motors, asynchronous motors, DC motors, high-voltage motors, and many others, without any power or voltage limitations. For the winding of spindle motors and other motors, we utilize high-quality winding materials such as H-class enamel copper wire, F-class insulation papers, and other premium-grade winding components. With the combination of these quality materials and skilled workmanship, we can effectively solve the problems faced by our valued customers. Furthermore, after the winding process, all motors undergo insulation and surge tests using state-of-the-art testing equipment to ensure the quality of the performed work. This guarantees the quality of the process. As a result of our confidence in this quality, we provide a one-year warranty for all our servo motor repair, maintenance, and rewinding services.

One of the important tests that determine the quality of spindle motor repair and maintenance is the measurement of the insulation quality of the stator windings with respect to ground and between each other. All spindle motors that come to our workshop for repair and maintenance undergo pre- and post-repair coil insulation tests to measure and record the insulation quality. The measurement of insulation quality in stator windings is crucial for the following reasons: To determine whether the enamel coating on the conductive copper wire has been burnt due to the heat generated during motor operation. To assess whether the insulation papers, which protect the phases from each other, have retained their insulation properties over time. To detect any damage caused by dust, dirt, oil, or other contaminants that accumulate on the coil windings. During the assessment of the insulation quality of spindle motor windings, it is not sufficient to conduct a basic insulation test using an ordinary insulation testing device against ground and between coil terminals. It is essential to perform a surge test, which examines for any leakage or short circuits between the windings. Our company utilizes a Baker brand HIPOT SURGE test device, which is one of the most important testing equipment in our technical infrastructure, to perform all the necessary coil tests and measurements on spindle motors with high quality and reliability.

Mechanical issues account for a significant portion of spindle motor failures. According to statistics, approximately 65% of electric motor failures worldwide are attributed to mechanical problems. Due to the production pressures on machines where spindle motors are used, they are often not given adequate downtime for regular and periodic maintenance. This lack of maintenance contributes to serious mechanical problems and subsequent motor failures. If these mechanical issues are not identified in a timely manner, they can lead to: Damage to the bearing housings in the front and rear motor covers Damage to the motor bearings Damage to the front and rear bearing housings of the rotor shaft Damage to the keyway in the rotor shaft Damage to the coupling and pulley locations on the rotor shaft Failure to address these mechanical problems promptly and adequately can significantly prolong and increase the cost of repair and maintenance processes. Changing the bearings of spindle motors requires extra attention. Due to the high operating speeds, the material properties, cage structures, and lubrication types of the bearings used may vary. It is crucial to use the same type and specifications of bearings. The tightness tolerances of the bearing housings should be measured with precision, and if any issues are detected, they must be meticulously addressed. Our company has an advanced technical infrastructure that enables us to efficiently and effectively resolve all mechanical problems. Additionally, with our in-house lathe workshop equipped with turning machines and Castolin Thermal Spray technology, our skilled technical personnel can coat and process the rotor shaft bearing housings, as well as the motor cover bearing housings. This enables us to expedite the repair and maintenance processes and provide our customers with fast and guaranteed service in a cost-effective manner.

We conduct dynamic drive tests on all spindle motors that undergo maintenance and repair in order to observe and measure their mechanical performance. The purpose of this test is to assess the accuracy and quality of the mechanical processes and interventions performed on the spindle motors during maintenance and repair. Additionally, vibration and imbalance measurements are carried out during this stage to evaluate the performance of replaced bearings and the accuracy and quality of mechanical interventions on the motor, as well as to measure the imbalance of the spindle motor. These measurements are performed using SKF CMXA 80 vibration analysis devices available within our company, ensuring seamless and high-quality results. Any observed issues are promptly addressed. These tests and measurements are recorded in video format and shared with our customers. Motors that pass the drive tests successfully are delivered to our customers, ensuring their reliable operation upon arrival. This guarantees the smooth functioning of the motors for our customers.

We subject all serviced, maintained, and repaired spindle motors to a dynamic drive test to observe and measure their mechanical and electrical performance after maintenance and repair. The purpose of this test is to assess the accuracy and quality of the mechanical and electrical interventions carried out during the repair and maintenance stages. It is a crucial step following the completion of spindle motor repairs, including the adjustment of encoders and sensor devices to ensure their proper functioning, measurement of current and voltage values to evaluate coil quality, verification of correct stator winding if performed, measurement of thermistor values to monitor sudden changes in coil temperature and ensure accurate readings, and analysis of various details to assess the accuracy of electrical interventions. Additionally, vibration measurements of the spindle motors are conducted during this stage to evaluate the performance of replaced bearings, the accuracy and quality of mechanical interventions on the motor, and the balance of the spindle motor. These measurements are carried out using our company's balance benches and vibration analysis devices in a reliable and high-quality manner. The test and measurements are recorded in video format and shared with the customer. Motors that successfully pass the drive test are shipped to our customers, ensuring their seamless operation upon arrival.

All spindle motors that undergo repair and maintenance in our facility have their rotor balances checked and inspected. The purpose of this inspection is to identify any imbalances that may occur in the rotor structure due to deformation and changes over time, and to perform necessary interventions. Imbalances resulting from high operating speeds in spindle motors can lead to damage in the bearings, as well as in the bearing seats on the rotor shaft and motor covers. If these damages are not detected in a timely manner, the disintegration of the bearings can cause the rotor to rub against the stator, resulting in damage to the windings and laminated core, increasing the repair process and costs. The rotor balances obtained using Schenck balancing machines, a leading brand in the world of balancing equipment, are highly reliable and of high quality. Furthermore, after the external balancing process, the spindle motors are assembled and subjected to dynamic drive tests. During this process, any remaining imbalance observed in the final measurements taken using our SKF CMXA 80 vibration and balancing measurement device is addressed on-site in our workshop. These tests and measurements are recorded on video and shared with our customers. Motors that successfully pass the drive tests are then sent to our customers, ensuring trouble-free operation upon their arrival.
