MZ Series Rotor Flange Slip Rings Overview

The MZ series slip rings are designed for rotor flange mounting without a through bore, enabling flange face mounting. Their design allows for a higher number of circuits and higher current capacity within the same outer diameter (OD) due to the absence of a center hole. The ample inner space facilitates inner wiring and integration of special shielding modules, enhancing stability and reliability. These slip rings are commonly customized for sensitive or encoder signal transmission.

Models and Dimensions

• Available models include MZ056, MZ056F, MZ086, MZ086F, MZ119, and MZ119F.
• Outer diameters range from 56mm to 119mm.
• Number of circuits varies by model: 1 to 48 for MZ056 series, up to 119 for MZ119 series.
• Current ratings per circuit range from signal level (2A) up to 10A.
• Voltage ratings up to 440VAC/VDC for smaller models and up to 690VAC/VDC for larger models.

MZ056 and MZ056F Series Specifics

The MZ056 series features flange end face wiring, while the MZ056F series uses flange side face wiring. Both have an OD of 56mm and support a wide range of circuit counts and lengths. Detailed part number lists specify configurations with varying numbers of rings and lengths.

• Working life and rotating speed vary by quality level: VC (15 million revolutions, 250 RPM) and VD (80 million revolutions, 1000 RPM).

Customization Options

Customization is a key feature of the MZ series, with about 60% of sales being tailored solutions. Customizable parameters include:

• Flange size, cable exit direction, and cable length for rotor and stator.
• Dimensions such as length, height, and outer diameter.
• Support for up to 200 rings for current or signal.
• Optional aviation plugs, terminals, and heat-shrink tubing.
• Hybrid slip rings combining servo control signals, power lines, and encoder lines for brands like Yaskawa, Panasonic, and Siemens.
• Support for mixed high-speed data transmission protocols including Ethernet, USB, RS232, RS485, Profibus, CanBUS, CANOPEN, DeviceNET, CC-LINK, ProfiNET, and EtherCAT.
• Integration of temperature control and thermocouple signals.
• Special environment adaptations such as quakeproof, high temperature (up to 500°C), high pressure (up to 110KV), military grade, underwater protection (IP65, IP68), and stainless steel housing.
• Hybrid pneumatic/hydraulic and electric slip ring combinations.
• High rotating speeds up to 10,000 RPM and maximum currents up to 5000 amperes.

Additional Notes and Recommendations

• Multiple 10A rings can be connected in parallel to increase current capacity (e.g., two 10A rings in parallel provide 20A).
• Signal (5A) and power (10A) rings can be freely combined and customized.
• Customization may extend delivery time by 3 to 15 days and increase costs by 30% to 50%.
