1. Soldering Leads to the DC Motor
ME 120 Mechanical and Materials Engineering Portland State University

2. Overview
The DC motor that we will use does not have any leads. We need to solder a red (positive) and black (negative) leads to the connections.

3. Temperature-controlled soldering iron and flux

4. Soldering work surface with vise

5. Helping Hands

6. Procedure Cut a length of wire Strip and tin the ends of the wire
Make note of polarity and remove old leads
Insert tinned wire through tabs and bend into position
Secure leads by soldering to motor tabs

7. Cut new lead wires

8. Strip the leads

9. Tin the leads

10. Remove the old leads and note the polarity

11. Motor supported. Extension wires in place

12. Bend the tinned wires around the supports

13. Secure the leads with solder
