Indramat servo motor repair is less expensive than Indramat servo motor replacement. Indramat servo motor repair should only be performed by an electrical technician with training and experience.Most Indramat servo motors have unique testing procedures dependent upon their model, features, operations, and prints; But the general process is performed by a technician who follows standard test procedures. Technicians performing Indramat servo motor repair should go through an extensive evaluation process to ensure nothing is overlooked. Servo motor repairs should be initially inspected for cosmeticdamage and taking photos prior to further processing is suggested.

All nameplate and preventative maintenance info should be collected by the repair technician and safely stored forfuture reference. Once these initial steps are complete, the Indramat servo motor should be meter tested before test running on a control panel; Meter testing is to prevent further damage to parts, winding, and insulation. The servo motor should then be connected to a test stand to check EMF (electromagnetic frequency), encoder or resolver feedback, and commutation alignment; These standard tests are to ensure functionality once the motor is installed into production.Servo motor repairs also need to be tested with an oscilloscope to create an operation print. Once an operation printout is generated, the technicianwill check for connection issues, magnet failure, winding failure, and perform a 100% component test.

IndramatServo Motor Repair – Steps

  • Visual inspection of cosmetics
  • Take photos of unit
  • Gather nameplate data and shaft dimensions
  • Inspection of all electrical and mechanical servo motor parts
  • Re-magnetize magnets when necessary
  • Re-manufacture outputflange using original flange and factory dimensions
  • Repair or rewind servo motor windings, insulation, connections
  • Steam clean and bake
  • Replace brush holder and brushes (or repair brush holder if obsolete)
  • Grounded to electrical testing
  • Surge testing of everywinding to at least 1500 volts
  • Armature bar to bar test; to determine any shorts or opens within the winding
  • Servo motor alignment
  • Installation of high-grade sealed bearings
  • Installation of double lip seals in the front flange
  • Replacement of all old seals, O-rings, gaskets and connectors
  • Two part epoxy coating for an added protection

Once testing is complete, the servo motor technician reassembles the unit for final testing. During the final test procedure, techniciansshould connect the motor to an inverter drive with and without a load. Running the servo motor on an inverter is to ensure complete functionality beforereturning to customer. Final testing of servo with an inverter also allows verification that the servo motor can operate at full voltage and withstand full load amps of the motor specifications.It’s also suggested that repair shops work closely with all servo motor manufacturers. Working closely with servo motor manufacturers allows foraccess todata sheets that are needed to ensure that the the servo motor performs equal to, or better than, the original equipment manufacturer standards.

Some repair shops only require technicians to perform a few of these procedures but all of them are suggested by Precision Electric. Most repair shopswho offer Indramat servo motor repair do not even perform the repair in their facility; Instead, they outsource the repair to a third party such as PrecisionElectric. Precision Electric recommends technicians who areinvolved in repair decisions, verify thatthe company you’re sending equipment to is the same company who performs the repair. Using a third party Indramat servo motor repair shop is risky, more expensive and has a longer lead time than going directly to the repair source.

Servo motor repairs performed by Precision Electric includes a 12 month in-service warranty. The PrecisionElectric in-service warranty begins the day the servo motor is put into production and ends 12 months later.

Lenze Americas VFD Drives are high-performance products used to optimize new and existing machinery for production. Lenze is one of the leading drive and automation specialists in the field of machine engineering. Rapidly changing times present manufacturers with new and varied challenges. To succeed in the future, manufacturers will need to handle more extensive tasks in even shorter time frames; Lenze Americas aims to reachthis ideal.

SMV Series:The SMV series of Lenze Americas VFD drives offer sophisticated auto-tuning and fast dynamic torque response. The SMV is designed for motor applications where dynamic speed and torque control is demanded. The SMV series isan attractive solution for a broad range of applications including: food processing machinery, packaging machinery, material handling, conveying systems, HVAC systems, and more.The SMV series uses an Electronic Programming Module (EPM) for programming. Maintenance techs can easily use the EPM to reconfigure drive parameters or reset the drive. When a drive reset is necessary on the SMV, customers can reset to factory default or preset settings within seconds. When SMV drives must be replaced, the parameter configuration can besaved by the user by simply plugging in the pre-programmed EPM.

MC1000 Series:The MC1000 Series of Lenze Americas VFD drives are the intelligent, versatile and cost-effective choice for industrial applications. From harsh environments to high torque loads, the M1000 Series drives meet the toughest requirements with reliability, at a low cost. Customers can easily program the MC Series and integrate extensive I/O with an array of programmable functions. The M1000 is available in power ranges of 1/4 to 150 HP. The MC1000 offersEnhanced Torque System (ETS). ETS allows maximum starting and accelerating torque and tight speed regulation, even under fluctuating load conditions. M1000 drives feature manual boost for high starting torque, and auto-boost for high torque acceleration at any speed. The M1000 features power-up & auto restart modes, sleep mode with adjustable speed threshold and time.The MC1000 also offers anoptional Form C Relay and Dynamic Braking.

M3000 Series
The M3000 series of Lenze America VFD drives are for process control demands with fast acceleration and response. The M3000 is rated for constant torque applications but can easily be configured for variable torque applications. Most Process Control drives are designed for variable torque applications where the motor is driving a centrifugal fan or pump. As such, these drives are limited to 110% current for overload situations such as acceleration or responding to a feedback change. The MC3000 is a true Constant Torque drive rated for 180% of rated current for 30 seconds and 150% for one minute. This allows faster response to system changes and the ability to apply the MC3000 to non-centrifugal applications such as compressors, conveyors and other constant torque loads. The M3000 is available in the same power ranges and voltages as the M1000.

MCH Series:The MCH series of Lenze Americas VFD drives are available from 1 to 250 HP. The MCH series were designed for the HVAC market and specific requirements of industrial and commercial installations. The MCH series are designed to operate standard induction motors. The MCH Series offers intuitive operator interface using simple programming and operational information. The MCH series allows drive software toadjust the motor speed to maintain a preset pressure, flow, temperature or other variables using PID setpoint control.The MCH Series include UL and cUL approved motor protection for single motor applications. The MCH Series isseen in applications such as fans, pumps and cooling towers.
