The SR3640-1562-1 accessibility is enhanced thanks to its gasketed conduit box, which houses a large wiring compartment for easy termination. With anti-cog magnets in its design, the motor ensures smooth low-speed operation without the risk of cogging. This feature also complements the motor's high over-current capacity, which, together with dynamic braking, safeguards the motor from damage. The device's polyester impregnated armature helps to bolster the motor's mechanical and electrical integrity. Weighing 27 lbs and measuring a total length of 12.13 inches, this motor's dimensions are essential considerations when it comes to mounting. The Tachometer Adapter Kit provides thorough guidelines that cover both the installation and the monitoring of the motor's speed over a wide range. The adapter makes it easy for users to install their GE, Servo-Tek, or Baldor tachometer. However, each type of motor requires a specific adapter, so it is always advised to contact the manufacturer for a safe operation.
