In a motor repair shop, or for new production motors, the Baker DX gives confidence that a motor is correctly wound and insulated, before it’s deployed in the field.

The standards-compliant surge test – a signature feature of Baker testers for decades – is the only test that can safely expose turn-to-turn insulation weaknesses. The Baker DX can find early indications of insulation weakness and faults in windings, between phases, coil-to-coil and in ground wall insulation. It can identify if contamination is impacting insulation strength. It can also detect problems with connections such as feed cable insulation weakness, motor imbalances, opens or high resistance.

The DX’s benefits can be extended to low-impedance coils, such as armatures, through the use of the Baker ZTX low impedance coil accessory. The ZTX, which includes the ATF5000 commutator probe accessory, allows the DX to apply surge tests to coils which require higher currents.

Baker Surveyor DX Software
Surveyor DX software enables Baker DX operators to use a personal computer to store more test data, generate and view reports across the full spectrum of Baker DX tests, and share and compare analysis with other maintenance personnel using data from multiple analyzers.

Definition of misalignmentLaser Shaft Alignment
Misalignment is the deviation of relative shaft position from collinear axis of rotation when
equipment is running at normal operating conditions.

How is misalignment recognized?
There are several symptoms indicating misalignment.

• Premature bearing, seal, shaft and coupling failure
• Excessive radial and axial vibrations
• High casing temperature at or near the bearings or high discharge oil temperature
• Excessive amount of oil leakage at the bearing seals
• The coupling is hot while it is running and immediately after unit shutdown. Look for rubber powder inside the
coupling shroud
• Loose foundation bolts
• Loose or broken coupling bolts
• Excessive amount of grease on the inside of coupling guard
• Similar pieces of equipment are vibrating less or seem to have longer operating life
• The shafts are breaking (or cracking) at or close to the inboard bearings or coupling hubs

Effects of base conditions and thermal variations
Even if you align your machines properly there is a risk that they break due to misalignment. If the foundation
where the machine is mounted is warped you may have a soft foot condition, i.e. one of the machine feet has a
poor contact with the floor. It is of major importance that this is corrected before performing the alignment.
If the alignment is performed when the machines are cold, and no compensation for thermal growth is considered, the machines will probably be running severely misaligned at running temperature.

The Fixturlaser shaft alignment tool allows for high precision shaft to shaft alignment which is superior to traditional methods of alignment such as straight-edge or dial-indication

  • Accurate to 0.001mm (1 mils)
  • Horizontal and Vertical Machines
  • All Shaft Sizes
  • Printing and Built in Memory
  • Thermal Growth Compensation
  • Real Time Measurements


Belt alignment, or more accurately sheave alignment, is the process of achieving proper radial and axial alignment of the centerlines of sheave grooves, onto which belts run. Historically, belt or sheave alignment has not been considered a major concern in maintenance, due to belt costs being relatively small. However, if sheaves are not properly aligned and tensioned, the following problems occur:

  • Greatly reduced life of the belts
  • Increased radial and axial loading of the shafts, and the bearings that support them
  • Increased wear and decreased life of the sheaves
  • Increased noise, vibration, dust, and heat due to belt wear.

In the past, sheaves were aligned using a straightedge or string, but this method can not accurately measure parallelism of the shafts. A more accurate method is the use of a laser sheave alignment tool.

At Ampro Electric we offer on site balancing, we can come to you facility and balance your equipment that has increased vibration. Our trained professional staff will come on site and balance your equipment to the required ISO specs using GTI Predictive maintenance field balancing software.

Unbalance is a leading cause of damage in rotating equipment. The stress overtime caused by imbalance leads to early failure and unnecessary downtime. Common causes of imbalance include: looseness, thermal changes, tooling changes, maintenance repairs, bent shafts, bowed shafts, and product build up (found commonly in blowers, compressors, and fans). Imbalance can also be an indicator of old equipment caused by corrosion or erosion of the bearings, rotors, or seals.

Everything from belt pulleys, fans, ventilators, couplings, compressors, blowers, motors, and other rotating equipment can benefit from being balanced.
