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. |

This is a standard European
motor, in North America we stock the 208-240V/440-480V 9 lead motor,
which would be the
TN71B/4 NA B14, all dimensions and performance the same, but 1.15
Service factor at these kW HP ratings due to the higher RPM. |
