Vertical Motors 101: Everything You Need To Know

Posted on by Kurz Industrial Solutions

vertical motorFor those of you who are familiar with electric motors, most people think of the std horizontal mounted motors we see everywhere in almost every application.  What you may not know is that there are also vertical motors. What you’ll see in this article is information on horizontal and vertical motors and some of the differences between them.

 

Differences Between Horizontal Motors and Vertical Motors

  1. Horizontal motors are used in many different applications such as pumps, conveyors, fans, and compressors. Horizontal motors are used in both variable torque and constant torque applications. Typical installations are as the name designated the motor is mounted with the motor shaft in a horizontal position but that is not always the case.  In certain applications, the motors can be mounted vertically.
  2. Vertical motors are used is fewer applications such as pumps and turbines and are primarily used in variable torque applications. You can get them in solid shaft and hollow shaft configurations and as the name designates the motors are mounted with the shaft down in a vertical position.
  3. The bearings systems are different between the two motor types. Horizontal motors use either ball or roller bearings designed to handle the rotor weights.  Vertical motors use single thrust bearings along with a single guide bearing. Thrust bearings can handle significantly more load than the bearings in a horizontal motor.

Typical Reasons for Failure

Bearings – Bearing failure is more often due to using the incorrect lubrication or too much of it.  Always follow the manufacturer’s recommendation for lubrication that meets your application. Consult the mfg. or a sales agent if you have questions.

Heat – When the heat exceeds the designed performance limits you will experience loss of product life span.  This means you are prematurely wearing out your motor windings.  This can happen when you undersize the motor for the application or improper insulation class for the temperatures you are operating the motor in.

Alignment – If you mount a motor and do not check that it is aligned properly you will potentially reduce the lifespan of the product you are using.   You will have heat issues and or bearing overload resulting in failure.  Take the time to do laser alignments or have your motor shop do it for you.

 

4 Ways to Improve your Product Life Cycle

– Install Grounding Rings

– Use Smart Sensors

– (PM) Preventative Maintenance Schedules

– Do alignment checks
