About MHMD042G1V - Panasonic A5 Break Motor

The

MHMD042G1V

is a 400-watt, high-inertia AC Servo Motor from the Panasonic MINAS A5 family. The primary difference between this model and the "G1U" model you asked about previously is that the G1V version includes a built-in electromagnetic holding brake.

Core Function

The main function of this motor is to provide safe, high-precision motion control for vertical axes or loads that must not move when power is cut.

Fail-Safe Holding: The built-in brake automatically engages when the motor is de-energized, preventing heavy loads from falling due to gravity.
High Stability: As a "High Inertia" motor, it excels at handling large or unbalanced mechanical loads that require smooth, vibration-free operation.
Precision Control: Equipped with a 20-bit incremental encoder (1,048,576 pulses/rev), it offers extremely fine positioning accuracy.

Weight & Dimensions in Inches

Because of the added brake mechanism, this motor is heavier and longer than the non-brake (G1U) version.

Feature	Inches (approx.)	Millimeters
Height/Width (Frame)	2.362"	60 mm
Length (Body only)	~4.72"	120 mm
Total Length (with Shaft)	~5.90"	150 mm
Shaft Diameter	0.551"	14 mm
Net Weight	3.97 lbs	1.8 kg

Technical Specifications

Power Output: 400 Watts (0.4 kW).
Rated Speed: 3000 RPM (Max 5000 RPM).
Rated Torque: 1.3 Nm (Peak 3.8 Nm).
Brake Static Friction Torque: 1.27 Nm or more.
Protection Rating: IP65.

The primary function of the MHMD042G1V is to provide safety-critical position control, specifically designed to lock the motor shaft in place when power is lost or the system is disabled.

While it performs the same high-precision motion as the previous models, its "V" designation signifies its specialized role in fail-safe applications.

Key Functional Roles

Holding Brake (Vertical Safety): The most critical function is its built-in electromagnetic brake. This is essential for vertical (Z-axis) applications where gravity would otherwise cause a heavy tool or robotic arm to crash down if the power failed.
High-Inertia Load Management: Like the "G1U" model, this motor is designed to handle "heavy" loads (loads with high mechanical inertia). It prevents the system from overshooting or vibrating when trying to stop a heavy moving part.
Extreme Precision: Its 20-bit encoder allows the system to "know" its exact position within 1/1,048,576th of a turn, making it functional for microscopic adjustments in high-end manufacturing.

How the Brake Functions

It is important to note that this is a holding brake, not a dynamic braking system:

Power On: The brake is energized and released, allowing the motor to spin freely.
Power Off: The brake is de-energized and a internal spring clamps the shaft.
Note: You should not use this brake to stop a spinning motor (which would cause wear); it is meant only to hold the position once the motor has already come to a stop.

Common Use Cases

Vertical CNC Milling: Holding the spindle head in place so it doesn't drop onto the workpiece during a power outage.
Automated Gates/Hoists: Ensuring a heavy load stays suspended safely.
Medical Imaging Equipment: Holding heavy sensors or X-ray arms in a fixed position for stable imaging.
