AC brake motor DFP

with built-in electromagnetic brakewith AC brakeself-braking

Overview
The DFP series are double-speed self-braking AC motors equipped with an electromagnetic spring brake featuring a double braking surface. These motors are engineered for precise brake release and engagement, high braking frequency and frequent start cycles. Brake feeding can be separate to allow operation with inverters or two-speed configurations.

Configurations

• Single three-phase winding in DAHLANDER/YY configuration (single winding) for motors with double polar pairs (2/4 and 4/8).
• Double internal three-phase winding for motors with polar pairs 2/6, 2/8, 4/6 and 6/8.

Polar couples and rotation speeds
POLAR COUPLES | ROTATION SPEED [rpm]
2/4 | 3000/1500
2/6 | 3000/1000
2/8 | 3000/750
4/6 | 1500/1000
4/8 | 1500/750
6/8 | 1000/750

Flange and general characteristics
These motors are available with B3, B5 and B14 flanges and have the following characteristics:

• IEC sizes = 63 ÷ 180
• Nominal power Pn = 0.18/0.12 ÷ 22/18.5 kW
• Brake type: A.C. current, D.C. current
• Energy efficiency = IE1
• Nominal torque Mn = 0.60/.060 ÷ 99.7/131.4 Nm

Compliance and manual release
All M.T. Motori Elettrici motors are provided with the screw for manual brake release and are manufactured in compliance with IEC international standards.
