2-Stage UDL 1.5kW – R57 Gear Motor

The 2-Stage UDL 1.5kW – R57 Gear Motor is a type of gear motor assembled from an electric motor-specifically a 3-phase electric motor-and a gearbox-specifically a 2-stage gearbox. Overall, the motor features a sturdy structure, good heat dissipation, and is optimized for applications requiring high precision and long-term stability.

General design of the 2-Stage UDL 1.5kW – R57 Gear Motor

Motor overview

• Speed variator (UDL – 1.5kW): The primary stage provides stepless speed adjustment via a mechanical friction disk mechanism, allowing smooth rpm variation without stopping the machine.
• Gearbox (R57): The secondary stage is coaxial, using high-efficiency helical gears. This design optimizes load-bearing capacity and offers superior durability compared to conventional worm gearboxes.

Operating characteristics

• Flexible speed adjustment: Fine-tune the output rotation within the allowable working range even while the system is running, meeting changing flow rates or line speeds.
• Efficiency & Smoothness: Utilizing helical gear pairs, the system operates extremely smoothly, generates minimal heat, and preserves power transferred from the 1.5kW motor to the load.
• Coaxial structure: The input and output shafts lie on a straight line, optimizing installation space and proving especially effective in agitators, conveyors, or linear drive mechanisms.

Detailed structure of the 2-Stage UDL 1.5kW – R57 Gear Motor

The 2-Stage UDL 1.5kW – R57 Gear Motor is assembled from a 3-phase electric motor 1.5kW 2Hp with a 2-stage UDL 1.5kW – R57 gearbox. Its detailed structure includes:

Electric motor structure:

• Solid cast motor housing with good heat dissipation through a finned system.
• Stator assembled from technical steel laminations, wound with high-temperature-resistant copper wire.
• Precisely dynamically balanced rotor ensures smooth and stable operation.
• Heat-treated alloy steel shaft resists warping and wear.

Gearbox structure:

• Stage 1 is a mechanical speed variator (UDL): Specifically, a 1.5kW 2Hp mechanical speed variator that alters input speed using a friction mechanism or gears before transmitting to the next stage.
• Stage 2 – R57 gearbox, specifically an R-Series Inline Helical Gearbox thanks to its special construction featuring a robust, sturdy casing and high lifespan.
• Housing, shafts, and lubrication system: Cast iron housing, shafts rotating on ball bearings; gearbox oil is used for lubrication, friction reduction, and heat dissipation.

Technical specifications of the 2-Stage UDL 1.5kW – R57 Gear Motor

The 2-Stage UDL 1.5kW – R57 Gear Motor is a transmission solution combining a 3-phase electric motor, a UDL mechanical speed variator, and an R57 inline gearbox. This design allows users to proactively adjust output speed according to specific operational requirements while ensuring stable and precise torque transmission.

Technical specifications of the 3-phase electric motor 1.5kW 2HP

The 3-phase electric motor 1.5kW 2Hp features a compact structure while fully meeting continuous working demands. The flange-mounted style allows the motor to easily connect with the mechanical speed variator and other transmission equipment.

Technical specifications of the UDL 1.5kW 2HP mechanical speed variator

The UDL 1.5kW mechanical speed variator allows changing the rotational speed via a stepless friction disk mechanism. As a result, the system can flexibly meet various working modes without needing an additional variable frequency drive.

Technical specifications of the R57 inline helical gearbox

The R57 inline helical gearbox plays the role of converting the speed from the speed variator into an output speed suitable for the load. The multi-stage helical gear structure helps the transmission device operate efficiently, reduce noise, and increase durability when operating over long periods.

Applications of the 2-Stage UDL 1.5kW – R57 Gear Motor

Thanks to its inline shaft design and flexible speed adjustment capability, the UDL – R57 motor is suitable for various industrial equipment such as:

• Product transportation conveyors in production lines.
• Mixers and agitators requiring slow speeds and high torque.
• Automatic feeding systems with adjustable speeds according to demand.
• Packaging machines, labeling machines, and sorting machines requiring high stability.

Instructions for installing an electric motor with a mechanical speed variator and an R gearbox

• Step 1: Begin by attaching the flange part of the mechanical speed variator directly to the end of the R gearbox. Carefully rotate it slightly so that their shafts fit together completely, and the two flanges must mesh precisely without gaps or jamming.
• Step 2: Lift the electric motor, aligning the motor shaft straight with the shaft hole of the mechanical speed variator. Then, push the electric motor firmly and decisively inward so that the motor body tightens snugly against the flange of the mechanical speed variator.
• Step 3: Insert the screws into the threaded holes around the contact position between the motor, mechanical speed variator, and R gearbox. Proceed to tighten all of these fixing bolts to keep the components from shaking loose or slipping off during operation.

Note: Absolutely avoid letting the shaft become misaligned or tilted, because when the machine runs at high speed, it will cause violent vibration and damage the internal gear teeth. Always place the equipment on a fixed flat surface during operation.
