4075011125 AC Motor Servo For Homag Machine 0.43NM 400V O-BREMSE 4-075-01-1125

When a Homag machine loses holding power at a stop position, the motor and brake are the first place to look. The 0.43 Nm torque and O.BREMSE brake on this unit are sized for controlled stopping and holding. A failed brake or a motor that no longer holds position stops the cycle where it matters.

This is a 400V AC servo motor, part number 4-075-01-1125 or 4075011125, rated at 0.43 Nm with an O.BREMSE brake. It fits Homag woodworking machines. To confirm the fit, match both part numbers against the motor you are replacing and check the nameplate on the old unit for the 400V supply and 0.43 Nm rating.

Check the brake wiring and the mounting face before installation. The O.BREMSE option means the brake releases when powered and holds when the motor stops. That behavior affects how the axis holds position after a stop. Confirm the drive is set for a 400V motor and that the brake circuit matches the old installation.

Supply comes as the motor unit only. No packaging or customisation details are stated. Send the machine model, the old motor's nameplate photo, and both part numbers with your enquiry. That lets the supplier confirm you receive the 4-075-01-1125 with the O.BREMSE brake before shipping.

What the specification fixes, and what it leaves to the machine:

• Holding at stop positions — The O.BREMSE brake holds the motor when power is off, so the axis stays put after a stop command.
• Torque match for light axes — At 0.43 Nm, the motor suits machine functions that need controlled motion without excess force at the shaft.
• Supply voltage check — The 400V rating means you confirm the drive output and existing wiring before connecting the replacement motor.
• Part number cross-check — Both 4-075-01-1125 and 4075011125 appear on the motor, so you can match either number to your machine records.
• Homag machine fit — The motor is intended for Homag woodworking machines, so check your machine model against the old motor before ordering.
• Brake release behaviour — The brake releases when powered and engages when the motor stops, which affects how the axis holds position between cycles.
• Mounting face check — Compare the mounting face and shaft of the old motor with the replacement before fitting to avoid a mismatch.
• Stable operation — A servo motor rated at 0.43 Nm keeps motion stable on axes that need repeatable stopping and holding during the cycle.

What changes on the shop floor once the unit is in place:

• Holds position after stop. The O.BREMSE brake keeps the axis from drifting when the motor is not powered, so the machine stays where you left it between cycles.
• Matches the original rating. A 0.43 Nm torque rating means the replacement matches the motor the machine was set up with, so drive settings stay close to original.
• One number to order. The 4-075-01-1125 and 4075011125 part numbers both identify this motor, so you can order from either your parts list or the nameplate.
• Built for Homag machines. The motor is intended for Homag woodworking machines, which means the mounting and connection points are made for that machine family.
• 400V supply match. Checking the 400V rating against your drive output before installation avoids a mismatch that would stop the machine at startup.
• Stable stopping. The brake option gives a reliable hold at stop positions, which matters on automated woodworking machines where exact positioning is critical.
• Clear enquiry path. Sending the old nameplate photo and both part numbers with your enquiry lets the supplier confirm the brake option and voltage before shipping.
• It replaces a manual step. A brush, a pot and a bench are all the unit needs; the glue is metered by the roller instead of by hand.
