Panasonic MHMD042G1U Servo Motor
The Panasonic MHMD042G1U is a medium-inertia AC servo motor from the MINAS A5 family, designed for general-purpose industrial automation applications requiring balanced dynamic response and reliable positioning. With a rated output of 400W and 200V AC power supply, this motor delivers consistent performance for applications including pick-and-place equipment, small robotics, packaging machinery, and automated assembly lines.
Key Features
- 400W Power Output: 400W rated output with 200V AC power supply, power supply capacity of 0.9 kVA
- Medium Inertia Design: Rotor inertia of 0.67 × 10⁻⁴ kg*m² for balanced dynamic response and load matching; recommended load inertia ratio of 30:1 or less
- 20-bit High-Resolution Encoder: 1,048,576 pulses/revolution resolution for precise positioning and smooth low-speed operation
- IP65 Protection Rating: Excellent protection against dust and water jets (excluding output shaft rotating portion and leadwire ends)
- Robust Torque Output: Rated torque of 1.3 N*m, momentary maximum peak torque of 3.8 N*m
- Wide Speed Range: Rated speed of 3000 r/min, maximum speed of 5000 r/min
- Lead Wire Configuration: Simple lead wire type for easy installation without additional connectors
- Durable Construction: Key-way shaft with center tap and oil seal for reliable torque transmission
- No Holding Brake: Standard version without brake (brake-equipped model MHMD042G1V available)
- Unlimited Regenerative Brake Frequency: No limit with or without optional external regenerative resistor DV0P4283
- RoHS Compliant: Confirmed to not contain the 6 substances specified in EU RoHS Directive
