INTRODUCTION

In the world of maintaining technical machines, sometimes you need to replace the motor to make the machine go faster or slower based on specific speed preferences. This article is here to help technicians identify, understand, and replace motors in a step-by-step way.

Identifying the Motor:

When thinking about changing a machine's motor in a technical setting, the goal is usually to speed up or slow down the machine. This decision depends on the desired speed. To figure out the motor's speed, just look at the label on the motor. Check the RATIO information, which is usually at the top.

• RATIO: 1:17 means Standard Speed
• RATIO: 1:10 means High Speed

The motor label also has other details like voltage (VOLTS), amperage (AMPS), motor horsepower (HP), recommended capacitor for single-phase motors (CA), and the motor's orientation found in the Part Number (MEMO).

To know the motor's orientation, check the part number. If it ends with 'L,' it's a left motor, and if it ends with 'R,' it's a right motor.

28110M17L: LEFT, STD SPEED     | 28110M17R: RIGHT, STD SPEED

28110M10L: LEFT, HIGH SPEDD  | 28110M10R: RIGHT, HIGH SPEED

TOOLS NEEDED:

1. Phillips Screw Driver (Recommended P2X4)
2. Allen Key M5
3. Allen Key M3
4. Adjustable wrench
5. Pliers

HOW TO CHANGE THE SIDE BELT MOTOR

Here are the step you should follow to replace the side belt motor

1.- Safety First: Disconnect the machine from the power source to ensure safety.

2.- Identify the Motor: Determine the type and specifications of the motor that needs to be replaced. Make note of the motor's model number and any other relevant details. Use the motor label to identify this information.

3.- Remove the Motor: Using the Allen key M5, carefully extract the four screws securing the motor.

Exercise caution throughout this process, ensuring to support the motor with your hand or another suitable fixture. It is crucial to hold the motor securely because once the last screw is removed, the motor may fall if not properly supported.

4.- Remove the Wiring from the Motor: Remove the cover from the wires and proceed to disconnect the four wires (three lines and one ground) extending from the machine's electrical cabinet to the motor.

5.- Motor Coupler: Utilize the Allen key M3 to detach the coupler from the previous motor. Subsequently, employ pliers to remove the key from the shaft.

Once these two components are removed, proceed to install the key and the coupler onto the new motor. Ensure that the placement distance of the coupler matches that of the previous motor.

6.- Connecting the Wires to the New Motor: Connect the wires to the new motor following the numerical order (do not forget to connect the GND wire as well).

Once you have connected the wires and closed the cover, use the adjustable wrench to tighten the cable gland connector securely.

7.- Installing the New Motor: Position the new motor and ensure that the coupler of the side belt aligns with the coupler on the motor (the blue spacer must be positioned in the middle of both).

Next, reinstall the four motor screws using the two top brackets to secure the motor to the machine.

8.- Power On and Final Check: Reconnect the machine to the power source and perform a final check to ensure the machine operates smoothly with the new motor.

NOTE: If the motor is spinning the side belt in the opposite direction, follow the instructions located on the wire cover. Flip out the blue wire and the yellow wire, that change is going to invert the direction of the motor. Remember, it is crucial to unplug the machine from the power before performing this adjustment.
