Exploring Indramat MDD Motors

Indramat MDD motors are digital AC servomotors tailored for precise motion control in systems when used alongside the manufacturer's digital drive controller. This pairing forms an efficient and responsive automation setup, which is particularly effective in high-feed rate cutting applications demanding exceptional contouring accuracy at high speeds.

MDD motors are offered with options for blocking brakes and come with output shafts available in plain or keyway configurations. They feature dual winding sets and a laminated core embedded with permanent magnets using either iron oxide or rare earth magnetic materials, enhancing electronic commutation and resulting in motors with reduced inertia.

The performance of all MDD servomotors is robust, marked by high reliability and maintenance-free operation thanks to lifetime-lubricated bearings, a brushless configuration, and completely sealed casings. Integrated temperature sensors within the motor windings help monitor and manage the heat to prevent damage from overload.

Designed to function optimally in a temperature range from 0°C to 45°C and at elevations from sea level up to 1000 meters, these motors perform best under specified ambient conditions. It's critical not to exceed these limits, as doing so can reduce the motor's performance; the maximum operating temperature and installation altitude should not surpass 55°C and 5000 meters respectively.

MDD Servomotors Applications

There are nine categories of MDD servomotors divided into three groups based on the machines they serve and their specific applications. These motors are highly suitable for functions involving screwing, dynamic operations, and high-precision tasks, and are employed in various machines including:

- Tool changing equipment

- Roller feeds

- Nibbling machines

- Pressing and punching machines

- Grinding machines

FAQs

What types of bearings are used in MDD servomotors?

MDD servomotors utilize two kinds of bearings: Side A is equipped with a floating bearing that absorbs radial forces, while Side B features a fixed bearing that deals with axial forces.

What mounting orientations are compatible with MDD motors?

MDD servomotors are versatile in installation, supporting any orientation which allows them to be mounted horizontally or vertically. When mounted vertically, the output shaft may face either upwards or downwards.

How does the blocking brake function in MDD servomotors?

The blocking brake in MDD servomotors works on a closed circuit principle. When no current is applied, a magnetic force engages the brake armature disc. The drive controller activates this blocking brake as required to control motion efficiently.
