trodeks® is pleased to announce the additionof NEMA size 23, 24 and 34 stepper motorswith IP65 ratings for operation in severeenvironmental conditions.The OMHW series are dust proof andresistant to low pressure water jets, andare ideal for applications in wet factoryenvironments such as the food and beverageindustry or outdoor use. Key features includea nickel plated brass cable gland, sealedlaminations, and front shaft contact seal.All models have an internal corrosion-resistantfilm coating as standard.IP65 specifies a product that is dust tight(no ingress of dust; complete protectionagainst contact) and protected against waterjets (water projected by a nozzle from anydirection shall have no harmful effects).

Important Note About Motor Current vs Drive Current:
When setting the drive current, you should multiply the stepper motor's nameplate current by 1.2. This provides the correct conversion from the motor's full-step nameplate rating to the drive's current setting.If the motor nameplate current is specified as 5 Amps, set the drive current to 6 Amps (5 x 1.2) to achieve full performance.

The OMHW stepper motors are 8-lead motors, offering the flexibility of either series or parallel connection. The motors should be series connected for best torque at low speeds, and parallel connected for best torque at higher speeds.

Motor Wiring --- Parallel Connection (8-lead motors):
Drive A+ = Orange + Black/White
Drive A- = Black + Orange/White
Drive B+ = Red + Yellow/White
Drive B- = Yellow + Red/White

Motor Wiring --- Series Connection (8-lead motors):
Drive A+ = Orange
Drive A- = Black
Drive B+ = Red
Drive B- = Yellow
Connect Orange/White to Black/White (not connected to drive)
Connect Red/White to Yellow/White (not connected to drive)
