Input Power Source
- Voltage: Will the motor be required to operate using AC or DC voltage? What voltage do you need your motor to run at?
- Frequency: Will it need to operate using 50Hz, 60Hz or both?
- Current: Does the current draw need to be under a specific value?
- Control: Will the motor need to run at variable speeds? What type of control will you need?
Environment
- Ingress Protection (IP): Will your motor need protection against the elements? Dust / water / etc?
- Temperature: What will the ambient temperature of the application’s environment be? Will operators need to touch the motor?
Gear-Motor Specs
- Weight: Are there any weight restrictions within your application?
- Life Expectancy: How long will you need your motor to operate for? Does the application allow for maintenance to be carried out?
- Noise: Is noise an important factor in your application?
- Efficiency: How important is your motor’s efficiency?
Gear-Motor Performance
- Speed (RPM): Will it need to operate at high or low speed? Will the speed be continuous, or will it vary?
- Power (W / HP): What is the Watt / Horsepower requirements? Are there limitations to the maximum current if using a control?
- Torque (Nm / in-lb): Will it require high start or stall torque? What are the running torque requirements?
- Duty Cycle: Will it need to operate continuously or in short bursts with time to cool down in between?
General Requirements
- Mounting Orientation: How does the motor need to be mounted to the application?
- Overhung and Size Loads: Does the application have additional loads (radial or axial) putting stress on the motor?
- Package Size: Is there a size restriction within your application?
- Lubrication: Is grease or oil required? Will the application require high or low temperature lubrication?
- Agency Approvals: Are there any agency approvals that your application must meet? E.g. UL, CE, RoHS, CSA or others?
