Choosing the right electric motor for a specific commercial or industrial application can be challenging due to the vast array of sizes and options available in the marketplace.

 

For example, will a general-purpose motor adequately serve your specific needs, or do you need a washdown-rated unit?

 

Are you powering a conveyor or HVAC equipment?

 

Are the duty cycles continuous or intermittent?

 

Choosing the right electric motor can be complex, requiring careful consideration of 8 different factors unique to your business or industry. To assist you in your electric motor decision process, we’ve listed those factors with a brief explanation below. Additionally, you can call us at 1-800-713-0103 or email us and allow one of our electric motor experts to guide you through the selection process.

 

 

Electric Motor Orientation

 

Most industrial motors fall into one of two categories.

 

Horizontal AC electric motors are typically used for conveyors, compressors, pumps, and other equipment that require reliable and continuous power under demanding conditions.

 

Vertical AC electric motors are designed and built to withstand thrust loads and the weight of rotating parts. These specialized features allow them to work efficiently in demanding environments.

 

 

Electric Motor Torque

 

Torque is required for startup and accelerating loads to a specific rate within a set time. The goal is to ensure the motor can power the equipment without excessive strain or power usage.

 

 

Electric Motor Speed

 

Depending on their design and construction, some electric motors are better suited for high-speed applications, while others are superior for low- to moderate-speed needs. Some applications may require adjustable speed controls to manage torques and rotation based on changing load size.

 

 

Voltage

 

The motor voltage must match the power source connections available in your facility. Smaller electric motors may require only a wall socket, while larger industrial motors require connection to the power grid via an electric sub-panel or an inline disconnect device.

 

 

Duty Cycles

 

Most applications either run continuously or for short periods. The longer the anticipated run time, the higher the duty cycle required to avoid power loss. The operational environment temperature must also be considered to prevent overheating during operational cycles.

 

 

Electric Motor Enclosure

 

Operational conditions impact which type of enclosure should be used to provide maximum motor protection. Examine the areas surrounding the electric motor location to determine if the motor will be exposed to dirt, dust, debris, moisture, or excessive heat. This will help you decide which enclosure option is best for your needs. For example, food and beverage locations typically utilize stainless steel castings to protect against spills or corrosion.

 

 

Operational Life Span

 

A motor’s operational lifetime can directly impact the lifespan of a connected tool or equipment. High-quality motors typically have a better ROI, lower maintenance costs, and last longer because they utilize superior internal components or assemblies. Regular maintenance and inspections can keep you running at peak performance across the motor’s lifecycle.

 

 

Capacity and Size

 

One key factor for determining the correct size is whether the motor will be permanently installed or moved from one location to another around the facility. The right electric motor must provide the torque necessary without generating more heat than the insulation can safely handle.

 

 

Additional Electric Motor Factors

 

In addition to the points outlined above, different industries or applications may require encoders & sensors, rotational controls, and climate protection factors as part of the motor selection process.
