Motor Flanges│Torque Arms│External Fans│

SEVA-tec GmbH is your specialist in the field of professional drive technology. The focus
is on three-phase motors, frequency inverters, and geared motors. You can order our drives
as energy-efficient motors in IE1/IE2/IE3 and IE4. Electric motors are often
required with specific requirements and corresponding accessories. Here we are the
ideal partner for you, because through our specialist staff in combination with an extensive motor inventory
and our own final assembly, we can offer you a wide variety of motor variants.

Electronic Braking Devices

Electronic brakes are used to brake asynchronous machines with squirrel cage rotor design and
1Ph AC capacitor motors within 10 seconds after switching off. For
external mounting, brake switches are available for 1.1kW, 1.5kW, 2.2kW, 3kW, 4kW, 5.5kW, and 7.5kW motors.

PTC Thermistor Protection

The drives offered here are predominantly prepared for temperature monitoring with PTC sensors
(positive temperature coefficient). To use this monitoring, you need the appropriate PTC tripping device.

The Design and Terminal Box

The design of the motors is variable upon request. Even with heavy-duty electric motors, i.e.,
from 4kW to 500kW, the motor feet can be modified. Thus, a foot-mounted motor B3 can also be
converted to a flange motor B5 or to a foot/flange motor B3/B5. Another advantage
is that the drive can be converted to a terminal box position with TB-top, TB-left, TB-right, or even
TB-bottom.
