Inner Diameter (Rotor): 140 mm (typical for PMA240)

Stack Length: 60 mm (standard for 1050 variant)

Continuous Torque: 1050 N·cm = 10.5 Nm

Peak Torque: 3150 N·cm = 31.5 Nm (3× rated, 10 s duty)

Rated Speed: 2000 RPM

Max Speed: 3000 RPM

Continuous Power: 2.2 kW (at rated speed)

Holding Brake: None (B-0 = No Brake)

Cooling Method: Liquid cooling (jacketed stator) — required for continuous rated torque

Feedback Options: Resolver, SINCOS, EnDat 2.2 (separately ordered)

Encoder Resolution: Up to 17-bit single-turn (with EnDat)

Insulation Class: Class H (180°C)

Magnet Type: Sintered Neodymium (NdFeB), N42SH grade

Winding: Copper, Class H varnish, epoxy potting optional

Weight: Approximately 12.5 kg (stator + rotor)

Structural Design:

• Stator: Laminated silicon steel, epoxy potted for vibration resistance
• Rotor: Bonded NdFeB magnets on carbon fiber sleeve
• Bearings: Not included — customer integrates into their own bearing system
• Shaft: None — direct-drive to customer’s mechanical interface

Key Features:

• Zero-backlash direct-drive torque motor
• No gearbox required — eliminates backlash, compliance, and maintenance
• High torque-to-inertia ratio for fastest acceleration
• Customizable cooling jacket for OEM integration

Applicable Industries: Wafer handling, gimbal systems, antenna positioning, direct-drive robotics, telescope mounts, surgical robots, aerospace actuation

Installation Requirements:

• Mount stator into customer-designed housing with interference fit or bolt pattern
• Rotor must be balanced to G2.5 (ISO 1940) or better
• Liquid cooling: 40% ethylene glycol / water, flow rate 2 L/min minimum, inlet temp 20–25°C
• Air gap: 0.3 mm ± 0.05 mm (critical — must be maintained)
• Feedback device mounted on rotor — cable routing through hollow shaft or slip ring

Usage Notes:

• Never operate without cooling at rated torque — thermal damage will occur within minutes
• Air gap must not drop below 0.2 mm — risk of rotor-stator contact
• Magnets are brittle — handle with care, no impact
• Requires custom servo drive tuned for frameless motor parameters
• Do not use as a conventional motor with gearbox — this is a direct-drive component
