The document discusses the Eco Drive Motor (EDM) which is an interior permanent magnet synchronous motor. It has several advantages over traditional induction motors such as being 54% smaller, 56% lighter, and having 5% higher efficiency. This leads to lower motor losses, reduced noise levels, extended bearing life, and lower energy costs. Implementation of EDMs across various drying operations could save an estimated 40% on annual energy consumption and costs with a payback period of less than 2 years.

4. EDM vs IM
IM has secondary derivative in the rotor. The
difference of induced magnetic field and rotor
speed by stator coil generates the voltage and
flows the current at secondary derivative, and
generates the torque.
EDM revolving magnetic field at stator coil
attracts and repel the rotor. The rotor turns at
synchronous speed. No electrical loss were
generated at the rotor. Therefore the reduction
of total motor loss improves the motor
efficiency. IPM motor able to get the benefit of
increasing torque effects.

Due to the reduction of total motor loss, the volume of cooling air flow is
reduced. EDM is more silent than IM.
