Motors & Variable Speed Drives

Чему вы научитесь

• Explain in plain terms how a three-phase induction motor produces rotation.
• Interpret every field on a motor nameplate, including kW, voltage, current, speed, duty, IP rating and insulation class.
• Compare direct-on-line, star-delta and soft-start starting methods and state when each is appropriate.
• Explain what a variable speed drive (VSD) does and why it saves energy on pumps and fans.
• Recognise the common motor failure modes — insulation breakdown, bearing failure and VSD-induced bearing currents — and the protection that guards against overload and single-phasing.
• Carry out routine motor checks and report early warning signs before they become failures.
