LEESON

LEESON is a brand of AC and DC motors and gearmotors manufactured by Regal Rexnord Corporation, a global industrial components company. The product line includes general-purpose AC motors, permanent magnet DC motors, parallel shaft gearmotors, and right-angle gearmotors. LEESON motors are available in a range of enclosure types: Totally Enclosed Fan Cooled (TEFC), Open Drip Proof (ODP), and Totally Enclosed Non-Ventilated (TENV). These enclosures provide protection against environmental contaminants such as dust, moisture, and oil, making them suitable for industrial applications where exposure to such elements is a concern. The motors are offered in various mounting configurations, including C-face, rigid base, and universal mount, allowing integration into different equipment layouts. Voltage options include single-phase and three-phase AC (115V, 230V, 460V, 575V) and DC (90V). Horsepower ratings in the catalog range from fractional (1/2 hp) to 2 hp, with speeds from 29 RPM to 3,450 RPM. Gearmotors feature parallel or right-angle shaft configurations with torque ratings up to 270 in-lb. LEESON motors are designed for continuous duty and comply with NEMA frame standards, ensuring interchangeability with other motors of similar frame sizes. 3G Electric stocks over 400 SKUs of LEESON motors and gearmotors, covering a broad spectrum of specifications. The inventory includes models from the Flex-In-1 series, which offers interchangeable mounting feet and C-face kits for field conversion. Each product listing on 3G Electric includes datasheets with full load current, RPM, voltage, and torque specifications. 3G Electric provides logistics support for global shipping, including export packaging and documentation. Procurement specialists and maintenance managers can request quotes for bulk or single-unit orders. The catalog is updated regularly to reflect current production models and discontinued items are phased out. For engineers specifying motors for pumps, conveyors, fans, or material handling equipment, LEESON offers a range of standard and customizable options. The brand is recognized for its adherence to NEMA standards and availability of replacement parts through 3G Electric's supply chain.

Common Applications

  • Conveyor systems — LEESON parallel shaft AC gearmotors (e.g., SKU 794AK9) for material handling at low speeds
  • Pump drives — LEESON Flex-In-1 3-phase AC motors (e.g., SKU 820HX5) for centrifugal pump applications
  • Fan and blower assemblies — LEESON general-purpose TEFC motors (e.g., SKU 801V99) for ventilation systems
  • Packaging machinery — LEESON right-angle DC gearmotors (e.g., SKU 794AY6) for compact indexing drives
  • Machine tool spindles — LEESON C-face ODP motors (e.g., SKU 53UF35) for lathe or milling machine power
  • Automated guided vehicles — LEESON permanent magnet DC gearmotors (e.g., SKU 794AT1) for drive wheels

Frequently asked questions

Common questions about LEESON from 3G Electric.

What enclosure types are available for LEESON AC motors from 3G Electric?

LEESON AC motors in the 3G Electric catalog are available in Totally Enclosed Fan Cooled (TEFC) and Open Drip Proof (ODP) enclosures. TEFC motors are sealed against dust and moisture, suitable for outdoor or washdown environments. ODP motors allow airflow through the windings but are not sealed, making them appropriate for clean, dry indoor locations. Both types are offered in C-face, rigid base, and universal mount configurations.

What voltage options are available for LEESON 3-phase motors?

LEESON 3-phase AC motors in the 3G Electric catalog are available in 230/460V AC dual-voltage and 575V AC single-voltage configurations. The dual-voltage models can be wired for either 230V or 460V operation, providing flexibility for different facility power systems. The 575V models are designed for 60 Hz operation and are common in Canadian and some industrial applications. Full load current ratings vary by voltage and horsepower.

Can LEESON gearmotors be ordered with specific torque and speed ratings?

Yes, LEESON gearmotors in the 3G Electric catalog are available with fixed speed and torque ratings based on the gear ratio and motor design. For example, parallel shaft AC gearmotors are offered with speeds from 29 RPM to 288 RPM and maximum torque from 100 in-lb to 270 in-lb. DC gearmotors are available with speeds from 31 RPM to 83 RPM and torque up to 220 in-lb. Each model has a specific gear ratio and output shaft configuration.

What is the difference between LEESON Flex-In-1 and standard general-purpose motors?

The LEESON Flex-In-1 series is a line of general-purpose AC motors that feature interchangeable mounting feet and C-face kits. This allows the motor to be converted from a C-face mount to a rigid base mount or vice versa without replacing the entire unit. Standard LEESON general-purpose motors have fixed mounting configurations. Both series are available in TEFC enclosures and similar horsepower and voltage ranges.

Are LEESON DC motors available with right-angle gearboxes?

Yes, LEESON right-angle DC gearmotors are available in the 3G Electric catalog. These are permanent magnet DC motors with a right-angle gearbox, typically TENV enclosure. For example, model M1135063.00 operates at 90V DC, 83 RPM, with a 30:1 gear ratio and 125 in-lb maximum torque. They are suitable for applications requiring compact mounting and high torque at low speeds.

How can I verify the specifications of a LEESON motor before purchasing?

Each LEESON motor listing on 3G Electric includes a datasheet with key specifications: brand, motor type, enclosure, nameplate RPM, full load current, voltage, and manufacturer part number. For example, SKU 820HX5 lists 3/4 hp, 575V AC, 3,450 RPM, and 1.6 A full load current. You can also request a quote for additional technical details or cross-reference the part number with the manufacturer's documentation.
