EMERSON® ULTRATECH™ VSM* MOTOR *Electronically Commutated Motor (E.C.M.) The Emerson® UltraTech™ variable speed motor is a four wire Electronically Commutated Motor (ECM) with two-way communication. Utilizing leading-edge technology, the motor receives commands from the Newmac VSM control board, executes the command and confirms that the command has been completed. It’s two-way communication made easier. FEATURES No special set-up or software configurations Permanent magnet DC with ball bearing and equipped with plug-in connectors Motor can be replaced by a standard UltraTech™ motor with no special programming required A large selection of CFM points for improved cooling and heating comfort Lower Electromagnetic Interference (EMI) than existing competitive motors Up to 50% better surge protection over competition Low speed settings give up to 2 decibels quieter operation than competition Significant power savings over existing PSC motors (up to 50%) or conventional motors (up to 75%)

EMERSON® ULTRATECH™ VSM* MOTOR/BLOWER ASSEMBLY The VSM blower/motor assembly uses either G10 or G12 blowers to give a full range of ramped heating and cooling cfm’s. FEATURES Belly band mounted Emerson® UltraTech™ motor can be operated by a 24V power connection on-board if VSM controller fails Standard 3.5 ton AC capability (3.0 ton for LFR) Optional 5 ton AC capability on NL2 model Quick connect 4 wire cable
