PMV Middle East - - DRIVETRAIN -

US-based drivetrain tech­nol­ogy com­pany Dana has un­veiled its com­pre­hen­sive Spicer Elec­tri­fied with TM4 port­fo­lio, in­clud­ing fully in­te­grated elec­tro-me­chan­i­cal propul­sion sys­tems fea­tur­ing gear­boxes, elec­tric mo­tors, in­vert­ers, and ther­mal-man­age­ment tech­nolo­gies.

Rang­ing from com­plete sys­tems and mo­du­lar so­lu­tions to in­di­vid­ual sub­sys­tem com­po­nents, Dana of­fers sup­port in de­vel­op­ing se­ries and par­al­lel hy­brid con­fig­u­ra­tions up to full bat­tery-elec­tric ve­hi­cles in the light ve­hi­cle, com­mer­cialve­hi­cle, and off-high­way mar­kets.

With the re­cent ac­qui­si­tion of TM4, Dana’s elec­tri­fi­ca­tion ca­pa­bil­i­ties now in­clude in-house de­sign and man­u­fac­tur­ing for elec­tric mo­tors, power in­vert­ers, and con­trol sys­tems. Com­bined with Dana’s ex­ist­ing core ex­per­tise in driv­e­line, seal­ing, and ther­mal man­age­ment, the com­pany em­ploys a sys­tems­fo­cused ap­proach to e-propul­sion, guid­ing elec­tric and hy­brid ve­hi­cle devel­op­ment for en­hanced per­for­mance, pack­ag­ing op­ti­miza­tion, and re­duced sys­tem weight.

Com­mer­cial ve­hi­cle man­u­fac­turer Karsan has in­cor­po­rated Dana’s TM4 Sumo MD elec­tric mo­tor and in­verter in its Karsan

ATAK elec­tri­fied midibus. The com­pany has been de­vel­op­ing sus­tain­able elec­tric-driven ve­hi­cles since 2015 and in­tro­duced its first pro­to­type elec­tric minibus, the Karsan JEST, in 2016.

The TM4 Sumo MD is com­posed of a high­torque, per­ma­nent mag­net vari­able re­luc­tance (PMVR) di­rect drive mo­tor and au­to­mo­tive­g­rade power elec­tron­ics. The new mo­tors with the PMVR tech­nol­ogy for ex­ter­nal ro­tors can de­liver 45% more torque and op­er­at­ing speed than pre­vi­ous mo­tors in the same com­pact pack­age, while re­duc­ing cost.

PMVR works by adding spe­cially-de­signed soft mag­netic com­pos­ites (SMCS) next to the mag­nets. SMCS are pro­duced through a new form­ing process and fab­ri­ca­tion method by TM4. The SMCS also al­lows the use of sim­pler and smaller mag­nets that are eas­ier to man­u­fac­ture and that uses less ra­reearth in the fab­ri­ca­tion process to ac­count for 25% sav­ings in mag­netic ma­te­rial. This new bus plat­form is able to op­er­ate with a range of up to 300km on a sin­gle charge.

Dana is also a key con­trib­u­tor in the devel­op­ment of the ve­hi­cle con­trol soft­ware, through the sup­ply of hard­ware and ser­vices re­lated to its TM4 Neuro 200 ve­hi­cle con­trol unit plat­form and Sy­napps devel­op­ment tool.

Jim Kam­sickas, pres­i­dent and CEO,

Dana, said: “Dana is uniquely equipped to pro­vide full e-propul­sion sys­tems across all gross ve­hi­cle weight cat­e­gories, plat­forms, and ar­chi­tec­tures. From fully in­te­grated e-propul­sion sys­tems that in­clude elec­tric mo­tors, in­vert­ers, gear­boxes, and ther­mal man­age­ment, to in­di­vid­ual sub­sys­tem com­po­nents de­signed to meet the in­di­vid­ual re­quire­ments of a cus­tomer’s ve­hi­cle, our Spicer Elec­tri­fied with TM4 so­lu­tions are rev­o­lu­tion­iz­ing power con­veyance and po­si­tion­ing Dana as a leader in the evo­lu­tion of mo­bil­ity.”

Dana has been col­lab­o­rat­ing with Me­calac to de­velop a cus­tom­ized e-drivetrain sys­tem for the new Me­calac e12 elec­tric com­pact wheeled ex­ca­va­tor.

Fea­tur­ing Spicer 112 axles and a Spicer

367 shift-on-fly trans­mis­sion, the Me­calac e12 wheeled ex­ca­va­tor de­liv­ers the range, per­for­mance, and com­pact size re­quired to sup­port modern ur­ban con­struc­tion sites.

Dana has a long his­tory of de­vel­op­ing drivetrain sys­tems for hy­brid and elec­tric ve­hi­cle ar­chi­tec­tures. The com­pany also of­fers patented bat­tery and elec­tronic cool­ing tech­nolo­gies, along with fuel-cell tech­nol­ogy. In ad­di­tion, Dana en­gi­neers had ex­ten­sive ex­pe­ri­ence with this par­tic­u­lar ap­pli­ca­tion be­cause the diesel-pow­ered ver­sion of this ve­hi­cle also fea­tures Spicer drivetrain com­po­nents.

Aziz Aghili, pres­i­dent of off-high­way drive and mo­tion tech­nolo­gies, Dana, said: "As a tier-one sup­plier, we un­der­stand that the suc­cess of elec­tri­fi­ca­tion in the off-high­way in­dus­try is driven by per­for­mance. These tech­nolo­gies must sup­port a smooth tran­si­tion to fully in­te­grated elec­tric-drive tech­nolo­gies op­ti­mized within a sin­gle pack­age, pro­vid­ing both elec­tri­fied and con­ven­tional pow­er­train op­tions. Dana's sup­port for new en­ergy ve­hi­cles has been con­sid­er­able, and grow­ing every year, as the im­por­tance of en­gi­neer­ing for hy­bridiza­tion and elec­tri­fi­ca­tion is fur­ther el­e­vated through­out the in­dus­try."
