Linear Motor Applications

Introduction to the application of M&D bilateral linear motor in cross-belt

In the cross-belt sorting system, the M&D bilateral linear motor plays a crucial role. It provides stable and powerful thrust for the entire system, is the core power source to ensure efficient sorting, and precisely controls its trajectory, and the M&D bilateral linear motor is perfectly adapted to these needs with its own characteristics.

Introduction to the application of M&D permanent magnet linear motor in narrow belt sorter

M&D's permanent magnet linear motors bring significant performance improvements to narrow-belt sorters. Narrow belt sorters are commonly used for fine sorting of various types of parcels and express mail, which have high requirements for the speed, accuracy and energy consumption of the equipment, and the permanent magnet linear motor can just meet these needs.

Why You Choose Our Linear Motor

Linear drive, efficient and accurate

High-performance parameter configuration to meet the power requirements of multiple scenarios

The permanent magnet linear motor has 200N continuous thrust and 400N starting thrust, and the speed range covers 0.8-3.0m/s, which can be adapted to the 2.5m/s high-speed sorting scene of the narrow-belt sorter. The maximum operating power of the bilateral linear motor is 5.5kW, the synchronous speed is up to 6m/s, and the static starting thrust is over 600N, which meets the heavy-duty and high-speed needs of the cross-belt sorter.

Highly compatible materials and structural design

The primary and secondary air gap range of permanent magnet linear motor is up to 6-10mm, allowing ±2mm installation error, adapting to mechanical structures with different precisions, and reducing the difficulty of installation and commissioning.

Open communication protocols and system integration capabilities

The permanent magnet linear motor supports Modbus RTU/ASCII communication protocol, is compatible with PLC, PC and other upper computers for centralized control, and can realize the networking linkage of 8 sets of motors through RS485 interface; The bilateral linear motor is suitable for Schneider, Siemens and other mainstream brands of 5.5kW inverters, supports V/f mode closed-loop control, and the speed fluctuation can be stabilized at ±0.02m/s, which is convenient for the upgrading and transformation of existing logistics equipment.

Questions For Linear Motor

Which logistics equipment is the permanent magnet linear motor suitable for?

Answer: It is suitable for applications such as cross-belt sorters, narrow-belt sorters, and linear sorters, meeting the precise driving requirements for scenarios like express parcel sorting, e-commerce warehousing, and cold chain logistics.

What are the typical applications of the double-sided linear motor?

Answer: It is mainly used in cross-belt sorters, especially for heavy-duty high-speed scenarios such as postal large-item sorting and airport baggage handling, capable of driving a 300kg load stably.

Can these two motors operate in low-temperature environments?

Answer: The permanent magnet linear motor supports an ambient temperature range of -30°C to 45°C, while the double-sided linear motor supports -30°C to 50°C, making both suitable for cold chain logistics scenarios.

What is the thrust and speed range of the permanent magnet linear motor?

Answer: Continuous thrust is 200N, starting thrust is 400N, and the speed range is 0.8-3.0m/s, capable of achieving a sorting efficiency of 8,000 items/hour.

What is the maximum power and synchronous speed of the double-sided linear motor?

Answer: Maximum operating power is 5.5kW, synchronous speed is 6m/s, and static starting thrust exceeds 600N.

What are the protection and insulation ratings of the motors?

Answer: The permanent magnet linear motor has an IP65 protection rating and Class F insulation, while the double-sided linear motor has an IP60 protection rating (expandable to waterproof) and Class F insulation.

What are the requirements for the installation air gap of the permanent magnet linear motor?

Answer: The air gap range should be 6-10mm, and protective tools must be used during installation. The secondary plate should be positioned before removing the protective packaging.

What are the requirements for the insertion depth of the double-sided linear motor's secondary plate?

Answer: The minimum insertion depth of the secondary plate is 130mm. Insufficient depth will cause thrust attenuation, so the depth must be ensured by adjusting the mounting bracket.

What is the temperature protection mechanism of the motors?

Answer: They are equipped with a built-in bimetal temperature protector (activated at 120±5°C). The permanent magnet motor additionally has a temperature switch that automatically cuts off power in case of overheating.

How to maintain the cooling system of the double-sided linear motor?

Answer: It adopts a heat sink + fan combination. Regularly clean foreign objects from the fan, as the fan has a lifespan of approximately 100,000 hours.

What should be noted in daily motor maintenance?

Answer: Avoid live operations and do not touch the motor within 5 minutes after shutdown. Check whether the secondary plate insertion depth and air gap meet requirements.

How to handle overcurrent alarms during motor operation?

Answer: This may be caused by excessive load or output short circuits. Check motor wiring, reduce the load, and for permanent magnet motors, the torque boost value can be decreased.

What are the possible reasons for insufficient thrust in the double-sided linear motor?

Answer: Incorrect secondary plate material (e.g., using 6061 instead of 6063), insufficient insertion depth, excessive air gap, or incorrect inverter V/f ratio settings.

How to resolve motor protector alarms?

Answer: This may be due to fan failure or overheating. Check fan operation, clean air ducts, and replace faulty fans if necessary.
