Drive-Tek Force Vent Units are supplied as standard with a capacitor so they can be wired as 230V 1PH AC or 400V 3PH AC which is very useful if being stocked as a spare part as one unit covers both 1/3PH motor supply
Drive-Tek Force Ventilation Units are designed to fit the the Drive-Tek range of AC motors in frame sizes from D63 to D160 (0.18kW to 18.5kW) (max 15kw 4pole) they can be supplied fitted to the motor of your choice or retro fitted by yourself. The Force Vent Unit has the option of an extension tube to extend the length if an encoder is fitted. Please be aware that different manufactures have different dimensions for the fitting of fan cowls and these are designed to fit the Drive-Tek range of motors we can supply Force Vent units to fit other brands on request.
Standard AC motors are designed for fixed speed operation and when used in conjunction with an AC Drive (inverter) they are subject to conditions which invariably reduce motor performance and life. Typically standard AC motors can operate over a 4: 1 speed range (50 to 12.5Hz) beyond this it is necessary to allow for lack of cooling due to the motor fan running slower and excess heat being created within the motor with the result of burning out the motor.
The easiest way to overcome this problem is to fit a Drive-Tek Forced Vent unit which is an independently powered fan unit that replaces the standard motor fan. The Drive-Tek Force Vent Unit overblows a constant stream of air over the motor and ensures optimal cooling regardless of operating speed.
Typically using a Drive-Tek Force Ventilation Unit with a standard AC Motor and a mid-range AC Drive (Inverter) then a 20:1 (50 to 2.5Hz) speed range should be possible without heat damaging the motor and with a high performance AC Drive (Inverter) and closed loop feedback (Encoder) then 100:1 speed range would be possible. Often referred to as a Inverter rated AC Motor or Variable Speed AC Motor(Always check the AC Inverter Drive performance figures)
