The DorGO 800 uses:

 A 24V DC internal motor with integrated gearbox

It is:

• Mounted inside the motor housing (head unit)
• Connected to the chain rail drive system
• Controlled by the PCB (including charger + control logic)

Core specifications

 Dortech specs:

• Motor voltage: 24V DC
• Motor power: 120W
• Drive force: 800 N
• Speed: ~140 mm/sec

 These define the motor’s real-world performance.

Electrical characteristics

Input (via control system)

• Supplied by:
  • Charger PCB + battery system
• System voltage:
  • 24V DC control system

Motor behaviour

• Runs on DC polarity switching
  • Reverse polarity → reverse direction
• Controlled by:
  • Relay or H-bridge on PCB

Current draw (typical for this class)

• Idle: ~1–2A
• Load: ~4–8A
   (consistent with 120W 24V DC motors)

How it works in the system

Mechanical design

Motor type

• Brushed DC motor (most common in this class)

Gear system

• Integrated reduction gearbox
  • Converts:
    • High speed → high torque
• Often uses:
  • Bronze or steel gear set

Output

• Drives:
  • Chain sprocket
• Provides:
  • Smooth, controlled motion

Battery integration (important)

Because it’s a 24V DC motor:

 It works directly with:

• Battery backup system (1.2Ah–3.5Ah)

During power failure:

• Battery → motor runs directly
• No inverter needed

 This is a key advantage over AC motors.

Performance characteristics

Force

• 800 N pulling force
   Suitable for:
• Doors up to:
  • 100 kg / 12 m²

Speed profile

• Soft start
• Constant run
• Soft stop

 Controlled electronically via RPM/load monitoring

Noise

• Relatively quiet:
  • DC motor + gearbox + chain system

Protection & control

The motor is protected by:

Electronic protection

• Overcurrent detection
• Obstacle sensing
• Auto reverse

Thermal protection

• Prevents overheating

Load sensing

• Detects resistance via:
  • Current draw / speed change

Typical failure symptoms

Motor failure

•  No movement, but control board alive
•  Clicking sound only
•  Burning smell

Gearbox failure

• Motor spins but:
  • Door doesn’t move
• Grinding noise

Partial failure

• Weak lifting power
• Slower operation

Replacement reality

This is where it gets practical:

 The DorGO motor is not always sold separately as a branded Dortech part

Instead:

• Often replaced as:
  • Motor + gearbox assembly
• Or substituted with:
  • Compatible 24V DC garage motor units
