誠岱機械廠股份有限公司 | CHENG DAY MACHINERY WORKS CO., LTD.

1. Motor Housing

• Apply Materials of gray cast iron (FC25) cast molding.
• The motor frame is sufficient strength structure, excellent vibration absorption, less deformation, enhances lifespan with precision and durability.

2. Encoder

• The encoder installation interfaces on the motor shaft in advance provide various options of traction machine.

3. Safety Handle Wheel

• The traction machine is operated through handle wheel drive pinions to drum gears while power off which could stop car cage smoothly on the nearest floor.

4. Wire Rope Wheel

• Apply materials spherical graphite cast iron (FCD650) on wheel with the hardness HB230~260.

5. Brake Release

• The manual brake release appropriate releases the break through handle wheel drive pinions to drum gears while power off which could stop car cage smoothly on the nearest floor.

6. Electromagnetic Brake

• Operation Frequency-1 million times and above.
• Low noise-60dB and below.

7. Safety Cover

• The security protection prevents that accident damage occurred during the wire rope operation.

Structure Description

• Apply cold silicon steel stator with F class insulation.
• Apply rare earth element of NdFeB permanent magnetic as the materials of permanent magnet
• Apply a self-alignment roller bearings on driving.
• Cooling by natural cooling.
• Apply QT-700 nodular graphite cast iron material on traction wheel.
• Apply electric disk brake on braking system.
