Choosing the right electric motor for your commercial or industrial application can be challenging due to the vast array of sizes and options available today. Choosing the best electric motor depends largely on your specific business or application.
For example, are the duty cycles continuous or intermittent?
Are you powering a conveyor or HVAC equipment?
Do you need a washdown-rated motor, or will a general-purpose motor do?
Choosing the right electric motor requires careful review of the different factors unique to your business or industry. We’ve listed those specific factors with brief explanations below to assist your motor selection process. If you still have questions, one of our electric motor experts will be happy to guide you through the selection process from start to finish.

Electric Motor Torque
Torque is essential for starting up and accelerating loads to a specific rate within a set time. The goal is to ensure the motor can efficiently power the equipment without excessive strain, heat buildup, or power consumption.
Electric Motor Orientation
Most industrial electric motors fall into one of two categories.
Horizontal AC electric motors provide smooth, reliable, and continuous power under demanding operating conditions. As a result, they are typically used in conveyors, compressors, pumps, and other types of equipment.
Vertical AC electric motors are designed and built to withstand thrust loads and support the weight of rotating parts. Their specialized internal components allow them to work efficiently in the most demanding environments.
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.
Duty Cycles
Most applications will either run continuously or for short periods. The longer the anticipated run time, the higher the duty cycle required to maintain efficiency while avoiding power loss. The operational environment temperature must also be considered to prevent potential overheating and damage to the bearings or wiring insulation.
Voltage
The motor voltage must match the power source connections available in your facility. Smaller electric motors may require only a J-box or wall plug, while larger industrial motors require connection to the power grid via an inline disconnect device or an electric sub-panel.
Electric Motor Enclosure
Operational conditions determine the type of enclosure that 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.
Capacity and Size
One key factor in determining the correct size is whether the motor will be permanently installed or relocated from one location to another within the facility. The right electric motor must provide the necessary torque without generating more heat than the insulation can safely withstand.
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.
