Stepper Motor

Place to aggregate motor information, mostly as it relates to microscopes

2018-05-28: creating page to aggregate industry pinout information and mcmaster recommendations.

Indexer connector (single)

BBB

mcmaster goal: come up with a standard connector to put on BBB cape

Goals:

• Requirement: fit 6 connectors on reasonable size BBB cape
• Use an existing standard
• COTS cables, or at least easily
• Shielded
• Durable

Main candidates:

• DB9

Durable connector COTS super available Shielded Breakout boards readily available No insustry standard pinout * I thought Gecko, but that's actually for the motors

• DB25

Industry standard connector * Single and multi versions However, too large

• Combicon style connector

Quick to make Can use shielded cables Can't buy whole cable, or at least will be expensive Wires can stress and fall off Used on Gecko and some others, although not consistently

DB25 (step/direction)

Above: Compumotor OEM650 pinout

Above: PMC VS Drive pinout

This seems to have been a de facto standard for some years. I've observed it on Compumotor, PMC, and other drivers.

mcmaster: IMHO this is too bulky to use in modern applications, although I do have several legacy drivers using it

IDC 5x2 (step/direction)

Used on some MDrive17 motors

mcmaster: of particular interest to me since I try to use these motors by default.

Indexer connector (multi)

Gecko DB25 (multi-axis indexer)

Above: G540 indexer connection

The G320X servo driver uses post mounted Phoenix contact type connectors.

Motor connector (power + data)

M12 connector (power + CAN)

M12/M23 seems to be common on modern stepper motors. The MDrive manual for example cites it was done to reach IP65 enclosure rating:

The MDrive17Plus2-65 Motion Control adds protection against the ingress of fluids and dust to the MDrive17Plus2 by changing the motor-drive enclosure to meet IP65 specifications. With this change the connector configuration changes to industry standard M12/M23 circular connectors.

• A-coding: actuator-sensor plug connections for DeviceNet, IO link and Profibus

DeviceNet is used my mcmaster MFCs

• B-coding: Fieldbus connections for Profibus and Interbus
• D-coding: Industrial Ethernet, Profinet, Ethernet/IP and EtherCat
• S-coding: Motor, Frequency-convertors, motor operated switches, PSUs for Power, 620V, 12A
• T-coding: Fieldbus comp, passive distribution boxes, motors, PSUs for Power, 63V, 12A
