VFD-required
Wide speed ranges with constant efficiency at partial load
Worldwide approvals, including CE, UL, CSA
Engineered to deliver efficient performance and reliable operation across various conveyor applications.
Match nameplate specifications: Record HP, voltage, frequency, RPM, frame size, mounting configuration, shaft dimensions. Photograph nameplate and mounting arrangement including bolt patterns and available clearances.
Document environment: Note ambient temperature range, washdown frequency, dust levels, hazardous area classifications. Environmental factors determine required enclosure and certification.
Verify compatibility: For gearmotors, confirm input shaft dimensions, mounting flange patterns, and load ratings match existing installation
New installations and upgrades
Calculate horsepower requirements: Use CEMA methods accounting for belt speed, material load, conveyor length, incline angle, and friction. Include starting torque for loaded startup conditions.
Select service factor: Specify 1.15–1.25 service factor providing margin for occasional overloads. Undersized motors overheat and fail prematurely.
Determine efficiency class: Specify IE3 minimum for conveyors operating more than 4,000 hours annually. Upgrade to IE4/IE5+ for 24/7 continuous duty.
Specify speed control: Fixed-speed applications use across-the-line starters. Variable speed requires VFD with inverter-duty motor specification.
Confirm environmental requirements: Specify IP rating, washdown capability, or explosion-proof certification matching facility conditions.
Conveyors operating more than 6,000 hours annually benefit from synchronous motor efficiency. Energy savings compound over years of operation, typically achieving payback within two years for continuous duty applications.
Distribution centers, material recovery facilities, and aggregate operations running 24/7 see the greatest return on investment.
Synchronous motors maintain constant efficiency at partial load and low speeds. Sortation conveyors, accumulation zones, and metering applications that rarely run at full capacity benefit from this characteristic.
Synchronous motors deliver higher power density than equivalent asynchronous motors, allowing smaller frame sizes for given horsepower ratings. Retrofit applications with limited mounting space can upgrade motor performance without modifying the conveyor structure.
A synchronous motor rotor locks magnetically to the stator’s rotating field, so rotor speed equals synchronous speed (no slip) as long as it stays in step.
Choose synchronous motors when:
Conveyors operate continuously (more than 6,000 hours annually)
Energy costs dominate lifecycle expenses
Facility targets maximum efficiency and carbon reduction
Application requires constant torque across wide speed ranges with VFD control
Typical applications: Trough idler conveyors in material recovery facilities, distribution center sortation systems, aggregate operations with 24/7 runtime.
An asynchronous (induction) motor rotor is driven by induced currents and always lags the stator field, so it runs at synchronous speed minus slip.
Choose asynchronous motors when:
Conveyors operate intermittently or less than 4,000 hours annually
Initial cost constraints prioritize lower upfront investment
Standard efficiency meets facility energy targets
Application requires broad serviceability
Typical applications: Slider bed conveyors for packaging, flat idler conveyors for sorting, tumble-back conveyors for metering.
Synchronous motors can be configured with the following features.
Motor brakes: Holding torque prevents rollback on inclined conveyors or during emergency stops
Incremental encoders: Speed feedback for precise speed regulation and position control (standard on IE5+ models)
External fans: Independent cooling for prolonged low-speed operation below 30 Hz
Temperature sensors (TF): PTC or RTD monitoring with early warning of overheating
Thermostats (TW): On/off switching at preset temperature thresholds
Space heaters (SH): Anti-condensation heating for humid environments
IP55 (standard): Dust ingress prevention, low-pressure water jet protection. Suits most indoor applications.
IP66 (washdown): Complete dust sealing, powerful water jet protection. For outdoor or washdown environments.
IP69K (steam cleaning): High-pressure, high-temperature steam resistance. For food processing with steam sanitization.
NEMA footed (B3): Standard foot mounting to flat surfaces
IEC footed: International standard foot mounting
NEMA C-flange: Direct mounting to North American gearboxes
Flange (B5/B14): Direct mounting to IEC gearboxes
Motor plug connections: Quick-disconnect wiring simplifies replacement
Sealed terminal boxes: Enhanced environmental protection at connection point
NXD tupH coating: Food-safe corrosion protection and non-porous surface that resists bacterial adhesion
We sell helical bevel drives, helical inline drives, parallel shaft drives, and worm drives for our motors. All gearboxes are available in washdown duty, explosion-proof, and corrosion-resistant options.
Pre-engineered motor-gearbox combinations arrive matched and aligned, eliminating field assembly time and alignment errors. We confirm ratio requirements, thermal ratings, and mounting compatibility before shipment. Complete drive packages can include factory-configured control systems and PLCs programmed for your specific gearbox assembly, providing plug-and-play conveyor control solutions.
Motor brakes are available factory-installed on gearmotors or as field-installed additions, matched to drive unit torque and duty cycle requirements. Control panels can be configured with variable frequency drives (VFDs), soft starters, and system programming tailored to your operational requirements.
