A4 750KW Servo motor and control box

The maximum speed of the motor is 2000RPM, the maximum running speed of the door is 1.95m/s , Ultra-high speed motors bring greater efficiency

Application scenario

The A4 series of door operator are designed for use with high speed rolling doors , high speed spiral track door , and high speed sectional panel lift door

Recommended application :

Loading dock , warehouse , distribution center , manufacturing facilities , Military facilities , Cold storage , Energy management , LEED Building

High-speed door operator speed response quickly from 0 to the fastest 2m/s only 500 milliseconds , in this interval can be stepless speed regulation , according to the need for arbitrary speed regulation, and steadily set smoth start and stop , so as to reduce the wear of the entire door system

The Servo system has a high-precision encoder and uses a closed-loop vector control algorithm to accurately calculate and control the speed , torque , and position of the door , thereby ensuring accurate and flexible operation of the door , There is no pause impact on the door body in acceleration and deceleration , hence extending the door life

Power supply :  AC 220V, 50/60Hz , single phase

Brake :  Integrated electric disk brake , electromagnetic power-off brake , with manual release function

Manual operation : Open the door with handle

Limit System:  High-precision absolute encoder : patented incremental and absolute integrated encoder , high accuracy , simple commissioning , no wear

Installation : Reducer flange installation , bracket can be installed on either right or left side of  the door , indoor mounting only

Size : The installation space : 16inches (460mm) of side space is required

Motor : PMSM AC permanent magnet synchronous servo motor , The motor uses rare-earth permanent magnet material , which is more efficient than traditional asynchronous induction motors , It has the advantages of energy saving , light weight , low temperature rise , large torque , and double overload , Door shaft direct-driven approach , less installation space

Warranty : 2years

Electrical accessories : sensor

Mechanic parts : wall mounting bracket

Reducer :  Modular highly integrated worm gear reducer

Drive : Door shaft driving directly

Electrical enclosure :  All electrical components are installed in a specific die-cast aluminum shell with Nema 1 protection rating , with good heat dissipation and corrosion protection

Door operator operation monitoring

The door operator has built-in sensors to monitor the running state of the motor to ensure it for long-term stable operation (see the description of the door control system for details )

Temperature range :

The operating temperature is between -10℃  and 40(60)℃

Compact Structure

It is very compact , the size and weight of the servo motor of the same power are reduced by 2/3, The PMSM servo motor uses NdFeB rare-earth material , providing a simple structure and a higher output power density
