Three-phase motor for continuous duty
The Dayton 48ZJ86 is a totally enclosed fan cooled motor built for general-purpose industrial use. It delivers 1 1/2 HP at a nameplate speed of 3465 RPM in a 56H frame with rigid base mounting. Dual-voltage windings accept 208-230V or 460V AC at 60/50 Hz for flexible installation.
Sustained operation at full load
Class B insulation and a 1.15 service factor allow the motor to run continuously at rated output in ambient temperatures up to 40°C. Ball bearings support the shaft for reliable rotation in either direction, while the steel frame resists vibration during extended cycles. Full-load current is 3.9 A on low voltage and 1.9 A on high voltage.
Replaces older 56-frame units
This model suits applications that need higher nominal efficiency than earlier designs, rated at 85.5 percent across the 3001-3600 RPM range. The jump is worthwhile when a process demands cooler running and lower long-term energy draw without changing mounting dimensions. No thermal protection is integrated, so external overload devices must be provided.

Questions about this item
How much heat does the 1 1/2 HP motor generate when running continuously at 40 °C ambient?
The motor is rated for continuous duty at a maximum ambient temperature of 40 °C with Class B insulation and a 1.15 service factor, allowing sustained operation within that thermal limit.
What voltage supply and wiring must I already have to install this 208-230/460 V three-phase motor?
You need a three-phase AC supply at either 208-230 V or 460 V, 60/50 Hz, with wiring sized for 3.9 A at low voltage or 1.9 A at high voltage, plus a rigid base for the 56H frame.
Will the 56H frame and 3465 RPM nameplate speed match the mounting and speed of my existing 56-frame equipment?
The 56H frame shares the same shaft height and bolt pattern as a standard 56 frame, and the 3465 RPM nameplate speed suits direct-drive applications designed for 3600 RPM synchronous speed.
