Types of Motors We Supply
Global Electronic Services offers a selection of various motors. Your company can get a replacement or new AC, DC or other types of motors in many popular brands.
AC motors run on alternating current and include synchronous and asynchronous types. These motors have a simple design that does not use brushes like some DC motors. Plus, the bearings should last for years if operated correctly. Because these motors are so popular and widely used worldwide for industrial purposes, finding a replacement is simple. The downsides of AC motors are their inability to operate at low speeds and less cost-effective speed controls.
Brushed and brushless DC motors use direct current to operate. The brushed design is common for use with torque control and variable-speed applications. For situations that require motors used in an environment with potentially volatile components, do not use brushed DC motors. The brushes could create sparks, leading to a dangerous situation. Brushes also require frequent replacements.
Brushless DC motors produce more power in a smaller space than AC or brushed DC motors. Therefore, these motors are an ideal option for power production in tight areas.
Other types of motors include servo motors, direct drive, linear motors and stepper motors. Servo motors include any motor that has a positioning sensor on it. These motors are critical components of automation equipment and robotics.
- – Direct drive motors have better technology, wear slower, accelerate faster and operate more efficiently than servo motors.
- – Linear motors create force along their length. Compared to more common cylindrical motors, these linear designs run more accurately and faster.
- – Stepper motors have teeth inside the rotor to create predictable movement. Each electric pulse moves the rotor a predetermined number of degrees. These types of motors work well in applications that make the most of the rotor’s stepped movements.

- – Machine tools
Common Questions and Problems for Industrial Motors
Industrial motors fail for several reasons. While some failures are repairable, others require replacing the unit. Common issues include the following.
Some installation problems can include shaft voltage, soft foot and pipe strain. These originate from poor installation of the motor. Unfortunately, if left ignored for too long, these issues may severely damage the motor, requiring replacement.
- – Shaft voltage problems happen when voltage along the shaft exceeds the bearings’ lubrication limits. This issue can lead to difficulties such as overheating and damaged or failed bearings. Testing the voltage during motor operation with a carbon brush probe can determine if this problem exists.
- – Soft foot is another installation issue with industrial motors. This problem occurs when the motor does not even have mounting on all feet. The misalignment can result from poorly installed mounting bolts or a surface that is not entirely flat.
- – Pipe strain happens when the drive and motor have incorrect alignment. Using a laser shaft alignment tool, someone from your company can determine if your motor has this problem and needs repairs.
Mechanical issues may stem from poor installation or improper operation of a motor. Examples include loose or imbalanced shafts, worn bearings and misalignment. Vibration testers and shaft alignment tools can diagnose these problems in motors.
Power Quality Problems
Power serving an industrial motor should be even and consistent. However, issues with the power’s quality may arise, producing problems with the motor’s operation. For instance, a transient voltage can happen when power surges or drops occur from weather conditions outside or nearby equipment powering on or off.
Problems with winding components, motor cables or terminations can lead to voltage imbalance. For a three-phase motor, a drop of voltage on one phase can cause a rise in the other two. Excessive voltage can wear down insulation. Using a three-phase power quality analyzer can identify this issue.
Finally, harmonic distortions may occur when unexpected AC voltage hits the motor winding. When this issue happens in excess, the motor may overheat. The same equipment used to identify voltage imbalances can also find harmonic distortions in your business’ motor.
Variable Frequency Drive Issues
Variable frequency drive issues may happen from overload, sigma current or drive output reflections.
Overloads may cause high temperatures, high current draw or slower torque. This problem is one of the most common reasons for motor failure. If a motor overheats, check for overload with a multimeter.
Sigma current happens in a motor when currents go where they shouldn’t. A four-channel oscilloscope can identify this problem.
Reflections on the drive output happen when the load and source impedance fall out of balance. This problem may happen with improper installation, old equipment or mismatched components. Because this issue can lead to wearing the motor wirings’ insulation, you should have someone in your company evaluate the motor first with a four-channel oscilloscope and fix any issues before the motor’s premature failure.
