Are Indramat MHD Motors Worth a Repair?

Indramat MHD synchronous servo motors are highly regarded for their robustness and long-lasting performance, largely due to their brushless construction. With lifetime lubricated bearings and a fully sealed housing, these motors are designed for low-maintenance usage and can operate smoothly for up to ten years before requiring a re-lubrication of the bearings. To ensure safety and optimal performance, these motors must be used with specific drive controllers from the manufacturer and require proper protective grounding.

Common Uses for MHD Motors

MHD motors are an efficient choice for automation across a variety of sectors, including:

- Printing and paper production

- Machine tool operations

- Handling and automation technology

- Food processing and packaging equipment

Notable Features of MHD Motors

MHD motors are equipped with several features that enhance their utility in automated systems:

- Easy and quick initial operation due to the encoder's built-in data memory

- High repeat frequencies accommodate regular start-stop activities

- Built-in temperature monitoring helps prevent overload

- The flange design simplifies installation onto machines

- They are capable of handling high radial loads, which allows for the direct attachment of belt pulleys and pinions

Considering Motor Repair or Replacement

When it's time to replace an MHD motor, consider opting for a factory repair or remanufacture, particularly since brand new MHD motors may not be readily available:

- Factory repairs are usually quick, often completed within 24 hours, making them much faster than acquiring a new motor.

- A professionally repaired motor can operate as effectively as a new one, thus enhancing your machinery’s performance.

- The cost of repairing a motor generally provides a more cost-effective solution than purchasing a new replacement.

Frequently Asked Questions

What are the installation options for the MHD motor?

The MHD motor is versatile in its installation and can be mounted either horizontally or vertically as required. For vertical installations, the output shaft can be oriented upwards or downwards.

Can the MHD motor operate in challenging environments?

Yes, the MHD motor is designed to perform under harsh conditions. Its fully enclosed construction and IP65 protection rating ensure its suitability for adverse environments.

What is the expected lifespan of the MHD motor's bearings?

Under normal operating conditions where radial and axial loads are within specified limits, the bearings of the MHD motor are projected to last for 30,000 hours of operation, in accordance with ISO 281 standards. Exceeding these load limits will result in a reduced lifespan for the bearings.
