1. Introduction
This manual provides essential information for the safe and efficient installation, operation, and maintenance of your Leeson M1115029.00 DC Gearmotor. Please read this manual thoroughly before attempting to install or operate the gearmotor. Retain this manual for future reference.
2. Safety Information
Always observe the following safety precautions to prevent injury and damage to the equipment:
- Electrical Hazard: Ensure all power is disconnected before installation, maintenance, or troubleshooting. Only qualified personnel should perform electrical connections.
- Moving Parts: Keep hands, clothing, and tools clear of rotating parts during operation.
- Overheating: Do not operate the gearmotor beyond its rated specifications. Ensure adequate ventilation.
- Mounting: Securely mount the gearmotor to a stable, rigid surface to prevent vibration and misalignment.
- Environmental Conditions: Operate the gearmotor within specified environmental limits (temperature, humidity). This unit is TENV (Totally Enclosed Non-Ventilated).
3. Product Overview
The Leeson M1115029.00 is a robust DC gearmotor designed for various industrial and commercial applications. It features a 1/20 horsepower motor, operating at 90V DC, and delivers a reduced output speed of 109 RPM with a gear ratio of 16:1. The unit is totally enclosed non-ventilated (TENV) for protection in demanding environments.

4. Setup and Installation
4.1 Mounting
The gearmotor should be mounted on a flat, rigid surface capable of supporting its weight and the operational forces. Use appropriate fasteners for secure attachment. Refer to Figure 3.3 for mounting dimensions and hole patterns.
- Ensure the mounting surface is clean and free of debris.
- Align the gearmotor shaft with the driven load to minimize stress on bearings and couplings.
- Tighten all mounting bolts to the manufacturer's recommended torque specifications.
4.2 Electrical Connections
WARNING: Disconnect all power before making electrical connections. Improper wiring can cause severe injury or damage to the gearmotor.
- Verify that the power supply matches the gearmotor's voltage rating (90V DC).
- Connect the positive (+) terminal of the DC power supply to the appropriate motor lead (typically red).
- Connect the negative (-) terminal of the DC power supply to the appropriate motor lead (typically black).
- Ensure all connections are secure and insulated.
- Consider installing appropriate overcurrent protection (fuses or circuit breakers) in the power circuit.

5. Operating Instructions
5.1 Initial Start-up
After completing installation and electrical connections, perform a test run:
- Ensure no load is connected to the output shaft initially, if possible.
- Apply power to the gearmotor. Observe for smooth operation, unusual noises, or excessive vibration.
- If any anomalies are detected, immediately disconnect power and refer to the Troubleshooting section.
5.2 Normal Operation
The M1115029.00 gearmotor is designed for continuous duty within its specified ratings. Monitor the gearmotor periodically for:
- Temperature: The motor housing should be warm to the touch but not excessively hot.
- Noise: Listen for any changes in operating noise, which could indicate wear or damage.
- Vibration: Excessive vibration can indicate misalignment or mechanical issues.
Avoid operating the gearmotor beyond its rated torque (27 Lb-in) or speed (109 RPM) to prevent premature wear or failure.
6. Maintenance
Regular maintenance ensures optimal performance and extends the lifespan of your gearmotor. Always disconnect power before performing any maintenance.
6.1 Routine Inspection (Monthly)
- Check for loose mounting bolts and retighten as necessary.
- Inspect electrical connections for signs of wear, corrosion, or looseness.
- Clean any dust or debris from the motor housing to ensure efficient heat dissipation.
- Examine the output shaft and any connected couplings for wear or damage.
6.2 Lubrication
The gearbox is typically factory-lubricated for life under normal operating conditions. Consult Leeson's official documentation or contact their support for specific lubrication requirements if operating in extreme conditions or after extended periods of use.
7. Troubleshooting
Before troubleshooting, ensure all power is disconnected. Only qualified personnel should attempt repairs.
