  The Above Photo is an MT Motor private labeled for ATTi, this one is a TFP71B/4 CA NM10 B5.  The series for this motor, TFP can be studied at this page: LINK TO BRAKE MOTOR PAGE   The TFP is the highest performance brake motor MT produces.  The CA on this nameplate indicates this to be a Alternating Current Brake (as opposed to CC which is DC current), it is preset to 10NM torque, and this one is a B5 flange mounting.  This motor is a 6 lead Delta/Star wired for 230/400V/50Hz and 440-480V/60Hz is acceptable voltage.  This motor is NOT suited for 208-240V/60Hz power, it will not perform to ratings on lower than required voltage.    The TVT replacement to this motor, for North American voltage, would be the TFP71B4 NA CA NM10 B5, would be a YY/Y wired 9 lead motor and AC brake suited for 208-240V and 440-480V/60Hz North American power.  This motor is also ATEX Ex II 3GS certified, UL/CSA/CE listed suitable standards for USA, Europe, and Canada respectively.
