Discontinued Product - Last buy: July 31, 2022. Special Order Product - Avoid exporting to Japan or via Japan.
Product Overview
The Panasonic MHMJ042G1V is a high-inertia AC servo motor from the MINAS A5 family, featuring a built-in holding brake for vertical-axis applications. With a rated output of 400W and 200V AC power supply, this motor delivers reliable performance for precision motion control in industrial automation applications including small robotics, Z-axis positioning, pick-and-place equipment, and automated assembly systems.
The motor features a 20-bit incremental encoder with 1,048,576 pulses per revolution resolution for high positioning accuracy, IP65 environmental protection against dust and water jets, and a built-in holding brake for position retention during power-off conditions.
Key Features
- 400W Power Output: 400W rated output with 200V AC power supply, power supply capacity of 0.9 kVA
- High Inertia Design: Rotor inertia of 0.70 × 10⁻⁴ kg*m² for stable 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
- Built-in Holding Brake: Integrated brake with 1.27 N*m static friction torque for vertical axis load holding - brake releases when energized
- IP65 Protection Rating: Excellent protection against dust and water jets (excluding shaft rotating portion and leadwire ends)
- Durable Construction: Key-way shaft with center tap and oil seal for reliable torque transmission and contamination protection
- Lead Wire Configuration: Simple lead wire type for easy installation without additional connectors
- Wide Speed Range: Rated speed of 3000 r/min, maximum speed of 5000 r/min for high-throughput applications
- Robust Torque Output: Rated torque of 1.3 N*m, momentary maximum peak torque of 3.8 N*m for demanding acceleration requirements
- 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 2011/65/EU
