Belt conveyor used PMSM

The asynchronous motor drive has the following problems:
Low power factor and high energy consumption;
Directly driven by electric power, large starting current;
The volume of the power supply transformer is increased, and the running is not stable when starting, which causes a certain impact on the belt;
Without special control equipment, with no monitoring data in real-time, so the centralized control effect is poor.
The reducer in the front has a large mechanical loss, low transmission rate, low operating efficiency, and large energy consumption.
The reducer is large, with a complex structure, high difficulty in installation, high failure rate, and heavy workload of maintenance;
Frequent lubricating oil change;
More investment in installation and maintenance costs, low-performance cost ratio.

Special permanent magnet direct drive motor for belt conveyor
The special low-speed high-power permanent magnet drive system for the belt conveyor is a high-efficiency and energy-saving direct-drive electric drive system, which directly drives the load equipment. Different from the traditional asynchronous motor, the selection of the system depends on the actual equipment speed range and the equipment load torque. The specific selection rules are as follows:

Determine the motor speed range according to the belt speed and roller outer diameter of the belt conveyor, to select the motor drive system whose speed range is not less than and closest to the actual demand. The standard rated speed is 0~60r/min, 0~75r/min, 0~90r/min, and other speed range can be adjusted and customized according to the actual requirements of customers.

Confirm the torque required by the belt conveyor first to select the appropriate permanent magnet drive system. The actual torque of the equipment can also be calculated according to the parameters of the traditional asynchronous motor and the speed ratio of the reducer.

Determine the rated voltage of the motor. The common voltage of the motor under the torque of 30000N.m is 380V, 660V, 1140V. The motor voltage above the torque of 30000N.m is 1140V, 3300V, 6kV, 10kV. Other voltage levels can be customized according to customer needs.

The motor cooling mode includes natural cooling, forced air cooling, and water cooling, which can be selected according to customers’ actual needs.

The motors can be designed and manufactured according to the technical parameters provided by users.

If the parameters of the motor are clear, they can be selected according to this Catalog Parameter List.
