Options For Motor Mounts And Stock Motors
Motor mounts allow direct coupling to the motor shaft on either the right (shown) or left side jack input shaft. For easy installation 2-ton through 20-ton wormgear style jacks are available with motor mount adapters for standard NEMAC-Face motors. Jacks supplied with motor mounts are available with and without NEMA C-Faced motors. When motors are included they come with the necessary hardware and coupling keys. Contact Joyce/Dayton for information about other types of motor mounts (i.e., IEC, pneumatic, servo motor, etc.).

All standard motors are 3-phase, 60 Hz., 208-230/460 VAC or 230/460 VAC. Other motor options are available. Maximum 1750 RPM input.

It is important to consider the input torque a direct drive motor must deliver at start up.
-
Brake motors (M2) are recommended for double lead jacks, ball screw jacks and actuators, and electric cylinders that are more than 30% efficient.
-
If the motor frequency will be varied to provide a “soft” start, an inverter duty motor may be needed.
