BODINE Electric 0618 Right Angle Gearmotor
This unit is a compact 1/8 horsepower drive designed for 115-volt operation, with a 20:1 gear ratio and 85 RPM output. Its 42R4BFSI-5L family designation signals a standard, versatile member of the AC right-angle lineup. Best for light to moderate loads in single-phase 115V systems. Choose this if you need dependable, straightforward performance in a compact package. A potential limitation is that higher-torque applications may require a higher HP model or lower speed target.
Leeson M1145039 Right-Angle AC Gearmotor
Leeson offers a permanent split capacitor design with a precision-machined aluminum gear housing. It runs on 115/230V and 60/50 Hz, allowing flexibility for international or mixed-use setups. The long-life worm gear with bronze wheel construction supports steady operation in a compact format. This model is best for general-purpose applications in factories or workshops that require reliable performance at common voltages. It’s especially suitable for tasks where quick, consistent speed reduction is essential. A limitation is that some users may need additional cooling for heavy-duty use over extended periods.
BODINE Electric 0623 Right-Angle Gearmotor
With a slightly higher current at 1.7 amps and the same 1/8 HP rating, this unit offers a 10:1 gear ratio for applications needing a bit more torque at lower speeds. Best for compact setups where space is at a premium but a bit more torque is required than the 20:1 configurations. Use this if you must fit within tight mechanical envelopes and still want dependable single-phase operation. A note: the lower gear ratio means higher output speed than some 20:1 models, which may not suit very slow-speed tasks.
BODINE Electric 0489 Right-Angle Gearmotor
This model is a compact 1/15 HP drive at 115 VAC with a 15:1 gear ratio and 20 lb-in output. It’s best for light-duty conveyors, small feeders, or precise positioning tasks where space constraints and modest torque are both key. The lower horsepower suggests which loads are feasible; avoid this option for heavy or high-torque duties.
BODINE Electric 0490 Right-Angle Gearmotor
This 1/15 HP unit delivers 20:1 gear reduction at 115 VAC with 27 lb-in output. It fits mid-range torque needs or tasks that require stable speed reduction without taking on a large footprint. Best for smaller automated lines or packaging tasks where space and moderate load are balanced. A limitation to watch is potential heat buildup in sustained high-load scenarios; ensure adequate cooling in enclosed spaces.
BODINE Electric 0630 1/4 HP Right-Angle Gearmotor
Engineered for higher torque at the same platform, this 1/4 HP drive operates at 230 VAC with a 10:1 gear ratio and hints at versatility for heavier packaging, small conveyors, or automated handling. Best for users who require more power in a single-phase AC solution. A limitation might be greater physical size and higher voltage requirements; ensure compatibility with existing electrical infrastructure.
BODINE Electric 2336 Right-Angle Gearmotor
This unit stands out with 3-phase operation at 230 VAC and a 280:1 gear ratio, yielding a very low output speed (6 RPM) suitable for precise, slow-motion tasks. Best for high-torque needs at extremely low speeds or for applications like machine feeds and micro-positioning. It is heavier and more complex than single-phase options, so ensure the control system accommodates 3-phase power. A limitation is the very low RPM, which may require different mechanical gearing for certain tasks.
Buying Guide: Key Considerations For AC Right Angle Gearmotors
- Power and torque: Match horsepower and torque to your load. Higher gear ratios reduce speed but increase torque; ensure the motor can handle sustained duty cycles.
- Voltage and phase: Choose single-phase 115 VAC for most small workshops, or 230 VAC for higher power needs. If you have three-phase power, 2336’s 3-phase option may be advantageous.
- Gear ratio and output speed: Consider the required RPM. Very low speeds (like 6 RPM) are possible with high gear reductions, while faster outputs require lower ratios.
- Physical footprint: Some models are compact, while others are larger due to higher HP or heavier gear housings. Ensure fitment within your equipment enclosure.
- Durability and cooling: Look for robust gear housings and, if possible, designs with sufficient cooling for continuous duty or enclosed spaces.
- Application environment: Choose corrosion-resistant finishes or sealed designs if used in humid or dusty environments.
Buying Questions And Answers
- Q: Which gearmotor is best for light packaging tasks on 115V? A: The BODINE 0618 or 0490 models are well-suited for light to moderate loads at 115V, with different gear ratios to fit speed needs.
- Q: Do I need three-phase power for high-torque tasks? A: For very high torque at low speeds, the 2336 model offers 3-phase operation, but verify your facility’s power availability.
- Q: How do I choose between 10:1 and 20:1 gear ratios? A: 10:1 provides higher output speed with moderate torque; 20:1 reduces speed further and increases torque, useful for conveying or precise positioning.
- Q: Can these motors operate in continuous duty without overheating? A: Cooling considerations vary by model; ensure adequate ventilation and avoid enclosed spaces when running near rated loads.
- Q: Are there compact options for tight installations? A: Yes, several 1/8 HP models (like the 0618 and 0623) are compact and suitable for space-limited setups.
- Q: Which model supports international voltage? A: The Leeson M1145039 supports 115/230V, offering flexibility for different power networks.
These AC right-angle gearmotors span a range of power, speed, and mounting needs. When selecting, prioritize load requirements, supply voltage, speed targets, and available space to ensure reliable performance over time.
