JR1000 Family of 1000V AC VFD Systems

Part Number

• A801001 (VF1001)
• A801002 (VF1002)

Description

This system can be configured for large and small shuttle cars, continuous miners, shearers and feeder breakers with each drive able to serve multiple functions.

Features

• Voltage ranges of 850V to 1260V, 3PH, 50/60 Hz available to accommodate most international customers.
• Multiple voltage outputs.
• Smart rectifier modules provide energy-saving regenerative braking down to stall which can be held indefinitely without inverter or motor overheating.
• Systems can be designed for air contact cooled or liquid cooled base plate.
• Closed loop flux vector and open loop flux vector modes for unsurpassed accuracy to allow low speed holding when descending, especially when proximity detection system requested.
• Analog reference input and/ or CAN Bus Communications is available.
• Maximum output frequency of 150 Hz.
• Adaptive under-voltage and overvoltage control.
• Radio controlled option is available.
• Cutter motor feedback to optimize tram speed.
• Full motor protection (overload, short circuit, lock rotor, Motor RTD, online, jam, phase loss, ground fault).
• Our AC drive has up to 2X starting torque compared to a DC motor.
• Infinitely variable speed tramming.

Saminco Cool-Torque Motors are available:

• AC or DC input
• 120V DC to 500V DC
• 230V AC to 1000V AC
• Air-cooled or liquid-cooled
• Internal encoders give closed loop control down to zero speed
• Low current draw of motor (low AMPS) will extend life of motor
• Torque and speed-sharing between motors with greater starting torque
• Proximity detection ready
