Model Identification: Each gearmotor configuration is identified by a model number, which includes the frame size and reduction ratio.

Important Notes: Users are advised to refer to page 49 for additional notes on gearmotor selection.

Specifications and Procedures:

Taper Grip Usage: The taper grip section cannot accept bending moments or thrust loads and should not be used with angle types.
Handling and Maintenance: Avoid using oil or grease on the taper grip to ensure proper transmission torque.

Taper Grip Assembly Procedure:

Prepare the machine shaft by ensuring it is clean and free of rust or protrusions.
Load the taper grip onto the reducer by applying a thin oil layer on the threaded portion.
Install the reducer onto the machine shaft, ensuring it reaches the predetermined position.
Periodically check bolt tightness after initial operation and every six months thereafter.

Torque Arm Types and Installation:

Three types of torque arms are available: Attachment, Banjo, and T-Type.
For high startup or stop frequency operations, use rubber bushes and disk springs to mitigate shock.

Motor Information:

Sumitomo's motors meet efficiency class IE3 standards, with brake motors available in IE1 and IE3 upon request.
Motors comply with various international standards, including EN60034 and IEC regulations.

Brake Voltage:

Standard brake control voltage is 230 V for motors running at 400 V.
Options for 400 V and 24 V DC brakes are available separately.

Specifications: The document provides detailed specifications for the Bevel Buddybox 4, focusing on the brake motor system.

Procedures: Wiring examples for quick brake with varistor are provided, emphasizing the importance of protecting external switch contacts with a varistor.
