Product Overview

Motor Type	Type	Applications	Features	Notes	Output Range	Motor		Controller
Motor Type	Type	Applications	Features	Notes	Output Range	Parallel	Right Angle	Controller
Induction Motor	EA-IMA EA-IMB	【Constant-speed continuous operation】 (24-hour use such as fans, pumps, mixers, conveyors with minimal load fluctuation)	Simple and robust structure. Three-phase types provide high efficiency and good starting characteristics single-phase types offer easy wiring.	Not suitable for large acceleration/deceleration or frequent forward/reverse cycles.	6～200W	LINK	LINK	-
Reversible Motor	EA-RM	【Frequent forward/reverse operation】 positioning, reciprocating motion, pushing applications	Excellent reversing response, minimizing overrun	Generates a lot of heat, so it has a short-time rating (ex. 30 minutes)	6～120W	LINK	LINK	-
Brake Motor	EA-BM	【Holding / maintaining stop】 lifting, vertical transport, safety stop	Stops and holds immediately when power is turned off, and maintains position even during power failure	Limitations apply regarding stop frequency and temperature environment	6～200W	LINK	LINK	-
Speed Control Motor	EA-AM	【Speed control】 flow control, tension control, synchronous feeding, frequent setup changes	Controller-integrated design for easy wiring with a wide adjustable speed range	Risk of overheating during ultra-low-speed continuous operation	6～200W	LINK	LINK	LINK
Reversible Speed Control Motor	EA-ARM	【Speed control + reverse】 positioning, reciprocating motion, pushing applications requiring adjustable speed	Combines speed control and reversing capability in a single unit.	Duty cycle and thermal limits must be considered in continuous use.	25～120W	*	*	LINK
Brake Speed Control Motor	EA-ABM	【Speed control +Brake】 vertical transport, lifting requiring speed adjustment and position holding	Allows speed adjustment while maintaining safe and stable stopping performance.	Not suitable for continuous operation under heavy braking conditions.	25～200W	*	*	LINK
Torque Motor	EA-TM	【Tension Control】 Winding, feeding, and pressing applications that require maintaining constant tension or pressure.	Maintains high torque even at low or near-stopped speeds	Generates significant heat → ensure operation within continuous torque rating and provide cooling	3~20W	LINK	-	-
