CPM-78-39 Mechanical Interface v1.0¶

Status: Public engineering evaluation reference
Release date: 2026-10-06

This page summarizes packaging information from the controlled CPM-78-39 mechanical drawing used for engineering review.

Warning

This page is not a manufacturing drawing. Final tolerances, mounting details and any configuration-specific deviation must be confirmed from the current controlled drawing supplied for the order.

Controlled Envelope¶

Item	Controlled value
Maximum body diameter	78.7 mm
Overall product thickness	35.8 mm
Product weight	600 g

Drawing-Level Interface Information¶

The controlled drawing includes defined output-side and housing mounting patterns, connector lead arrangement and dimensional tolerances.

For final design-in, request the controlled drawing rather than deriving production geometry from website images.

Configuration Boundary¶

The reviewed drawing represents the 39:1, 36 V, 200 W Hall-sensor configuration corresponding to the current CPM-78-39 public product record.

Driver, absolute encoder, communication and closed-loop control hardware are not treated as standard unless separately confirmed.

CAD and Controlled Drawing¶

A controlled 2D drawing is available.

A public simplified STEP model is not currently released for CPM-78-39.
