2 Agenda Intro/Session description Todays demands/motivations EMAG and Thermal modeling Combined workflow Examples

3 Motivation for Analysis Over the last decade it is noticeable that there is a growing need for electric machines with High torque or High power density along with a High efficiency demand or/and Reduction in size, weight, cost Leading to higher temperature gradients with a higher demand on the materials in general, but esp. on the insulation materials shorter lifetime expectation due to a higher risk of thermal damages (esp. in the insulation materials). A higher risk of demagnetization of the magnets Source graphics: NREL

4 Motivation for Analysis Component lifetime estimates [1]: 22% of failures due to thermal damages in insulation 17% further thermal damage in other components Lifetime depends on temperature history; Temperature depends on losses and cooling Insulation lifetime L can be modeled by the Arrhenius chemical equation [2]: L A Montsinger s rule taken from transformer oil and solid insulation materials shows that the lifetime L decreases by 50% with increase of temperature T by 10 K [3]: L T 10K 0.5 L T So insulation breakdown is likely to be the problem associated with high temperatures. This problem may be tackled by either improving the insulation material and allowing the temperatures to rise or improving the cooling performance of the windings and limiting the maximum temperature.

Weiers, T. and Vogesang, R., Insulation Failure Mechanisms of Power Generators IEEE, Electrical Insulation Magazine, 24(4) [2] Dakin, T.W., 1948, Electrical Insulation Deterioration Treated as a Chemical Rate Phenomena, AIEE Trans., Part 1, 67 [3] Binder, A., TU Darmstadt, EW, 2008, Script Large Generators & High Power Drives

5 Motivation for Analysis To accomplish today s demand the new machine designs have to eliminate the safety factors of the over-sizing designs of the past to finally ensure the requested high power densities. The need to have an optimized thermal design besides an optimized electromagnetic design.

6 Electric Machine Simulation Technology Electromagnetic Simulation Electrical/mechanical performance of design Design studies of different types of machine IMD vs. BDC Torque and efficiency requirements are met Build efficiency map for machine Detailed geometric design of components 2D/3D Optimize magnet position/shape/material Include a simple/conduction only thermal model Coupled Problem Thermal Simulation Understand the efficiency of the cooling system Optimize a flow paths for a given cooling system Predict maximum component temperatures at given different operating points Consider Conduction/convection/radiation system Include temperature dependent properties Machine Designer/Electrical Engineer Thermal analyst/mechanical engineer

7 Losses in Electrical Machines The heat generated inside the motor originates from two main sources: Electrical losses include the copper losses - also I 2 R losses - in the windings (heating effect due to copper resistance), core losses and (magnetic hysteresis (~ B k f) and eddy currents (~ B 2 f 2 ) in iron cores) eddy current losses in other parts of the machine being electric conductive, e.g permanent magnets, end shields, housing parts, Mechanical losses, such as frictional losses generated by the bearings as well as windage losses

12 Losses in Electric Machines Comparison of maximum temperature Heterogeneous Homogeneous Heterogeneous mapped losses lead to higher maximum temperatures

13 Data Transfer to STAR-CCM+ - Losses The B-field variation allows iron loss estimation GoFER of 72 rotor positions /elec. revolution Modified Steinmetz method in SPEED applies also to non sinusoidal currents Front part of the tooth sees stronger field variations which is reflected in the higher iron loss density The iron loss density can be visualized SPEED Select the Plot Tab 13

14 Data Transfer to STAR-CCM+ - Geometry SPEED geometry for: stator, slot windings, rotor, rotor bars. CAD geometry for: end-windings, endrings, all non-active components (fan, housing, etc )

16 Simulation Steady State Temperatures Rotor Bar Avg=148.4 C, End Ring 1 Avg=144.7 C, End Ring 2 Avg=147.6 C Shaft Min Temp=55.8 C, Shaft Max Temp=148.3 C SPEED model with rotor 148 C requires 52.5 % of copper conductivity for consistent losses and performance at this load point. 16

17 SPEED > STAR-CCM+ Industrial Example Comparison with Measurements Client measurements on aux and main winding at 2 circumferential locations, both for the fan (cold side) and exhaust (hot side) of the end winding. Compare with mean and standard deviation of temperature in outer 5mm of endwinding End Winding 2 (cold side) Measurement Simulation % Error Mean 91.5 C 93.1 C 1.74 % STD 1.88 C 2.14 C End Winding 1 (hot side) Measurement Simulation % Error Mean C C 0.45 % STD 3.03 C 1.30 C

21 Temperature Dependent Resistivity of Copper Winding Copper winding modeled with temperature dependent resistivity, results in higher local heating where the coil is hotter. Vented stator shows reduction in coil temp and total heat load from 197 W to 180 W of copper losses.
