Any SmartMotor™ can be offered with custom windings to achieve higher
speeds or greater torque and custom shaft lengths and diameters.
Please consult factory.
• Data derived under dynamometer testing at 42 V using a PS42V20AF
power supply.
• Connector
kits and cable options are available.
• SmartMotor™ servos have CE certification.
