In the whole range, from size 55 to 200, housings and covers are made of die-cast aluminum, the external bidirectional fans are made of plastic material and the fan covers in steel sheets. The dimensional and constructive characteristics of the motors conform to IEC, UNEL, CEI specifications. Apart from the standard flanges, reduced flanges are available.
Protection
- Size 55 – 132: IP55 (on request IP65)
- Size 160 – 280: IP54 (on request IP55)
- Size 315 – 355: IP44 (on request IP54, IP55)
Terminal box
In the foot mounted types, the terminal box can be located in three different positions. On the standard type it is located on the top, upon request it can be located on the right or on the left hand side. Standard and double speed motors are equipped with a six terminals board (12 upon request).
Insulation class
Windings are made of copper wire with double thickness enamelling and are subjected to vacuum impregnation. They are also class F insulated granting a maximum thermal margin of 155 °C according to the main specifications. For particular applications it is possible to supply (upon request) class H insulated motors. Specially treated motors suitable to operate in humid and corrosive ambients are also available upon request.
Single Phase Motors
Single phase motors are equipped with a run capacitor permanently turned on and connected to the auxiliary winding for starting. The capacitor is assembled inside a special box in plastic which is mounted on the place of the old aluminium terminal box.
High starting torque
In those applications where a high starting torque is required, single phase motors can be equipped (upon request) with an auxiliary capacitor which is connected only in the starting phase and allows a starting torque of 200%. Once the motor has been started, the auxiliary capacitor is disconnected by means of an electronic relay. Start frequency: 1 every 7 seconds.
Direction of rotation
Motors are supplied with anticlockwise rotation looking at the shaft.
Symmetrical winding
Upon request, single phase electric motors can be supplied with a symmetrical winding in order to allow them to operate in both directions of rotation without stopping the motor.
Motor with electric ventilation
Upon request, motors can be supplied with an additional ventilation system which is fed separately at V 230/50-60 Hz single phase and V 230-400/50 Hz three phase installed inside the fan cover.
Cover
Upon request a sheet cover can be applied on to the fan cover in order to make it dripproof and to avoid foreign matters.
Encoder
Upon request, the motors can be equipped with an incremental encoder series EH80C/P - EL63C/P.
