CHAPTER II
General Motor Replacement Guidelines
Electric motors are the versatile workhorses of industry. In many applica-
tions, motors from a number of manufacturers can be used.
Major motor manufacturers today make every effort to maximize
interchangeability, mechanically and electrically, so that compromise
does not interfere with reliability and safety standards. However, no
manufacturer can be responsible for misapplication. If you are not
certain of a replacement condition, contact a qualified motor distributor,
sales office or service center.
Safety Precautions
• Use safe practices when handling, lifting, installing, operating, and
maintaining motors and related equipment.
• Install motors and related equipment in accordance with the
National Electrical Code (NEC) local electrical safety codes and
practices and, when applicable, the Occupational Safety and Health
Act (OSHA).
• Ground motors securely. Make sure that grounding wires and
devices are, in fact, properly grounded.
Before servicing or working near motor-driven equipment, disconnect
the power source from the motor and accessories.
Selection
Identifying a motor for replacement purposes or specifying a motor for
new applications can be done easily if the correct information is known.
This includes:
• Mechanical requirements of the driven load
• Physical and environmental considerations
• Efficiency and economic considerations
• Electrical Characteristics and Connections
